Float Object Is Not Callable: Causes and Solutions in Detail
The float object is not callable error occurs when the programmer tries to call a floating-point value as a function. Remember, floating-point values are never callable.
In this guide, there will be discussions of the causes of this error and the fixes, along with examples. Let’s discuss this further!
Why Does the Float Object Is Not Callable Error Occur?
The float object is not callable error occurs when the programmer follows a floating point value with parenthesis. A function is donated by a set of parentheses which helps a function to run. Only functions can be called, not objects like floating points, do not return values, etc.
However, some other situations in which you can face this error are listed below:
- Named a variable “float”
- Forget to use an operand
- Syntax error
– Named a Variable “Float”
When the programmer names a viable “float” and later applies the “float” function in the program, this error message will occur. Therefore, naming a variable float is not the correct practice. Let’s understand this better with an example.
The program is about calculating the tips each waiter staff at a restaurant are due and then splitting the amount equally. The program starts with a statement of how many staff members were working on that particular day by applying the input() method.
working_staff = input(“How many staff were present today? “)
float = float(input(“How much tips were earned today? “))
due_staff = float / float(working_staff)
rounded = round(due_staff, 2)
In this program, the user has rounded the amount that every staff member is due to two decimal places. This program will print the rounded amount to the console. After running the program, the output will be the following:
How many tips were earned today? 300
Traceback (recent most call last):
File “main.py”, line 5, in <module>
rounded = round(due_staff, 2)
The program will give this error message in return. This is because the programmer assigned a floating point value to a “float” variable. Later, the programmer uses float() to convert a value to a float. Moreover, when the program has assigned “float” a numerical value; the code cannot call the float() function.
– Forget To Use an Operand
Another reason for the “TypeError: ‘float’ object is not callable” error message to occur is often due to a missing mathematical operator in the program. Let’s take the same example as above, but this time the program focuses on the restaurant giving its workers a bonus of 6% increase on all the tips earned in a day.
It means that the waiters will earn more money by the end of the day, depending on how much they earn in tips. Due to this change, the programmer will revise the formula for calculating tips and percentages.
staff_working = input(“How many staff were present today? “)
earned_in_tips = float(input(“How many tips were collected today? “))
staff_due = 1.06 (earned_in_tips / float(staff_working))
rounded = round(staff_due, 2)
The above code will calculate the amount each staff member is due by dividing the total amount earned in tips by the number of staff present. The program multiples this by 1.06 to calculate a 6% increase in the total tips due. Let’s see the output.
How many tips were collected today? 300
Traceback (most recent call last):
File “main.py”, line 4, in <module>
staff_due = 1.06 (earned_in_tips / float(staff_working))
The output showed an error. This is because the programmer forgot to use a mathematical operator in the program. As you can see, the value 1.06 is immediately followed by a set of parentheses, so Python treats it as a function call. Thus, causing an error to occur.
– Problem In The Function Definition
A problem in the definition of the function you are trying to call can also result in this error. For better understanding, we are adding a detailed example below:
# Taking the value of the function “areaasquare”
# In the variable name “areaasquare”
print(‘Area of the Square: ‘,areaasquare)
print(‘Area of the Square: ‘,areaasquare)
File “pyprogram.py”, line 7, in <module>
This error occurred by a problem in the function definition. While trying to calculate the area of the square, it overrides the function definition. The error line is: areaasquare = areaasquare(33,3.2).
– Syntax Error
Most of the time, syntax errors cause these error messages to pop up. Using the wrong function at the wrong time or mixing between objects and functions are all considered syntax errors. Some common errors that occur due to syntax issues are:
- Float’ object is not callable sum
- Float’ object is not callable max
- A float’ object cannot be interpreted as an integer
- Float’ object is not iterable Python
How To Solve the “Float Object Is Not Callable” Error?
In order to solve the “float object is not callable” error, the programmer has to be careful with the name they choose for their variable so that the program does not confuse the variable with the object. Moreover, ensure the correct usage of operands and syntaxes.
The solutions to this error are given below, with detailed explanations and examples. Firstly, go through all of the solutions, then decide which one suits you the most.
– Do Not Name a Variable “Float” Before Using the Float Function
To solve the float is not callable problem, the programmer has to rename their “float” variable.
staff_working = input(“How many staff were present today? “)
earned_in_tips = float(input(“How much tips were earned today?”))
staff_due = earned_in_tips / float(staff_working)
rounded = round(staff_due, 2)
Now, the program has a variable name of “earned_in_tips” and not “float”. Let’s see its output:
How many tips were earned today? 300
The program runs successfully, and each member will get $42.86 in tips.
– Always Use an Operand for Numeric Values
To eliminate this error message, the programmer should always use an operand for numeric calculations. If they miss it, the error will occur. Taking the example from above, the waiters will get a 6% bonus on total tips earned.
staff_working = input(“How many staff were present today? “)
earned_in_tips = float(input(“How many tips were collected today? “))
staff_due = 1.06 * (earned_in_tips / float(staff_working))
rounded = round(staff_due, 2)
The addition of the “*” operand has separated the 1.06 value and the math equation in the brackets. It is a symbol of multiplication.
Let’s see the output:
How many tips were collected today? 300
Each member of the wait staff will earn $45.00 from the tips. This includes the 6% bonus the restaurant is offering the waiters.
– Use the Correct Syntax
If the error still exists by correcting the above issues, then check the Syntax of every function the programmer has used. Moreover, correcting the syntax errors will solve other programming errors too. Some examples can be:
- Print ‘float’ object is not callable
- Int’ object is not callable
- Float’ object is not subscriptable
- The numpy float’ object is not callable
– Use the calculate_areaasquare Function
It is recommended to use the “calculate_areaasquare” function for numerical calculations such as square roots or areas. By changing the name of the function, the main function definition will not be affected, and the error will be avoided easily. Let’s take an example:
# Taking the value of the function “areaasquare”
# In the variable name “areaasquare”
print(‘Area of the Square: ‘,areaasquare)
The output will be:
Conclusion
After reading this article, you should be able to understand all the possible reasons and solutions for this particular error type. Here are some main points from this article:
- The float-point value is not a function, so it cannot be called.
- For float variables, always use operands. Doing so will prevent the Python typeerror.
- The “No Module named” error can also cause the float object not callable error to occur, especially if it has an object which is called.
- To resolve the error, the best way is to never name any variable as “float” before using the float() function.
- Ensure the programmer has used all the correct mathematical operands.
We are confident that you are now ready to resolve this error in their Python programs, just like a professional. Revisit this guide in case you get stuck at any point while fixing this error.
Python TypeError: Object is Not Callable. Why This Error?
Have you ever seen the TypeError object is not callable when running one of your Python programs? We will find out together why it occurs.
The TypeError object is not callable is raised by the Python interpreter when an object that is not callable gets called using parentheses. This can occur, for example, if by mistake you try to access elements of a list by using parentheses instead of square brackets.
I will show you some scenarios where this exception occurs and also what you have to do to fix this error.
Let’s find the error!
What Does Object is Not Callable Mean?
To understand what “object is not callable” means we first have understand what is a callable in Python.
As the word callable says, a callable object is an object that can be called. To verify if an object is callable you can use the callable() built-in function and pass an object to it. If this function returns True the object is callable, if it returns False the object is not callable.
Let’s test this function with few Python objects…
Lists are not callable
Tuples are not callable
Lambdas are callable
Functions are callable
A pattern is becoming obvious, functions are callable objects while data types are not. And this makes sense considering that we “call” functions in our code all the time.
What Does TypeError: ‘int’ object is not callable Mean?
In the same way we have done before, let’s verify if integers are callable by using the callable() built-in function.
As expected integers are not callable ��
So, in what kind of scenario can this error occur with integers?
Create a class called Person. This class has a single integer attribute called age.
Now, create an object of type Person:
Below you can see the only attribute of the object:
Let’s say we want to access the value of John’s age.
For some reason the class does not provide a getter so we try to access the age attribute.
The Python interpreter raises the TypeError exception object is not callable.
Can you see why?
That’s because we have tried to access the age attribute with parentheses.
The TypeError ‘int’ object is not callable occurs when in the code you try to access an integer by using parentheses. Parentheses can only be used with callable objects like functions.
What Does TypeError: ‘float’ object is not callable Mean?
The Python math library allows to retrieve the value of Pi by using the constant math.pi.
I want to write a simple if else statement that verifies if a number is smaller or bigger than Pi.
Let’s execute the program:
Interesting, something in the if condition is causing the error ‘float’ object is not callable.
That’s because math.pi is a float and to access it we don’t need parentheses. Parentheses are only required for callable objects and float objects are not callable.
The TypeError ‘float’ object is not callable is raised by the Python interpreter if you access a float number with parentheses. Parentheses can only be used with callable objects.
What is the Meaning of TypeError: ‘str’ object is not callable?
The Python sys module allows to get the version of your Python interpreter.
No way, the object is not callable error again!
To understand why check the official Python documentation for sys.version.
We have added parentheses at the end of sys.version but this object is a string and a string is not callable.
The TypeError ‘str’ object is not callable occurs when you access a string by using parentheses. Parentheses are only applicable to callable objects like functions.
Error ‘list’ object is not callable when working with a List
Define the following list of cities:
Now access the first element in this list:
By mistake I have used parentheses to access the first element of the list.
To access an element of a list the name of the list has to be followed by square brackets. Within square brackets you specify the index of the element to access.
So, the problem here is that instead of using square brackets I have used parentheses.
Let’s fix our code:
Nice, it works fine now.
The TypeError ‘list’ object is not callable occurs when you access an item of a list by using parentheses. Parentheses are only applicable to callable objects like functions. To access elements in a list you have to use square brackets instead.
Error ‘list’ object is not callable with a List Comprehension
When working with list comprehensions you might have also seen the “object is not callable” error.
This is a potential scenario when this could happen.
I have created a list of lists variable called matrix and I want to double every number in the matrix.
This error is more difficult to spot when working with list comprehensions as opposed as when working with lists.
That’s because a list comprehension is written on a single line and includes multiple parentheses and square brackets.
If you look at the code closely you will notice that the issue is caused by the fact that in row(index) we are using parentheses instead of square brackets.
This is the correct code:
Conclusion
Now that we went through few scenarios in which the error object is not callable can occur you should be able to fix it quickly if it occurs in your programs.

How to fix “TypeError: ‘float’ object is not callable” in Python
✋ Update: This post was originally published on my blog decodingweb.dev, where you can read the latest version for a �� user experience.
The “TypeError: ‘float’ object is not callable” error occurs when you try to call a floating-point number ( float object) as if it was a function!
Here’s what the error looks like:
Exit fullscreen mode
Calling a floating-point number as if it’s a callable isn’t what you’d do on purpose, though. It usually happens due to a wrong syntax or overriding a function name with a floating-point number.
Let’s explore the common causes and their solutions.
How to fix TypeError: ‘float’ object is not callable?
This TypeError happens under various scenarios:
- Declaring a variable with a name that’s also the name of a function
- Calling a method that’s also the name of a property
- Calling a method decorated with @property
- Missing a mathematical operator after a floating-point number
Declaring a variable with a name that’s also the name of a function: A Python function is an object like any other built-in object, such as int , float , dict , list , etc.
All built-in functions are defined in the builtins module and assigned a global name for easier access. For instance, sum() refers to the __builtins__.sum() function.
That said, overriding a function (accidentally or on purpose) with a floating-point number is technically possible.
For instance, if you define a variable named sum and assign it to the value of 88.6 , it’ll no longer point to __builtins__.sum() .
Exit fullscreen mode
If you run the above code, Python will complain with a «TypeError: ‘float’ object is not callable» error because 88.6 (the new value of sum ) isn’t callable.
You have two ways to fix the issue:
- Rename the variable sum
- Explicitly access the sum function from the builtins module ( __bultins__.sum )
The second approach isn’t recommended unless you’re developing a module. For instance, if you want to implement an open() function that wraps the built-in open() :
Exit fullscreen mode
In almost every other case, you should always avoid naming your variables as existing functions and methods. But if you’ve done so, renaming the variable would solve the issue.
So the above example could be fixed like this:
Exit fullscreen mode
Here’s another example with the built-in max() function:
Exit fullscreen mode
And to fix it, we rename the max variable name to max_value :
Exit fullscreen mode
Another common reason is accidentally overriding the range() function with a floating-point value before using it in a for loop:
Exit fullscreen mode
To fix it, we rename the range variable:
Exit fullscreen mode
⚠️ Long story short, you should never use a function name (built-in or user-defined) for your variables!
Overriding functions (and calling them later on) is the most common cause of this type error. It’s similar to calling integer numbers as if they’re callables.
Now, let’s get to the less common mistakes that lead to this error.
Calling a method that’s also the name of a property: When you define a property in a class constructor, any further declarations of the same name (e.g., methods) will be ignored.
Exit fullscreen mode
In the above example, since we have a property named price , the method price() is ignored. As a result, any reference to the price will return the property price . Obviously, calling price() is like calling 49.5() , which raises the type error.
To fix this TypeError, we need to change the method name:
Exit fullscreen mode
Calling a method decorated with @property decorator: The @property decorator turns a method into a “getter” for a read-only attribute of the same name.
Exit fullscreen mode
You need to access the getter method without the parentheses:
Exit fullscreen mode
Missing a mathematical operator after a float variable: In algebra, we can remove the multiplication operator to avoid ambiguity in our expressions. For instance, a × b , can be ab , or a × (b + c) can become a(b + c) .
But not in Python!
In the above example, if you remove the multiplication operator in a * (b + c) , Python’s interpreter would consider it a function call! And since the value of a is numeric (a floating-point number in this case), it’ll raise the error.
So if you have something like this in your code:
Exit fullscreen mode
You’d have to change it like so:
Exit fullscreen mode
Alright, I think it does it! I hope this quick guide helped you fix your problem.

Python TypeError: ‘float’ object is not callable Solution
Python supports a distinct data type to store floating points or decimal numbers, and that data type is known as Python float. Floating-point values are the numbers with decimal values, and Float is their data type.
Floating-point values are like other data types present in Python, but they represent decimal numerical values. But if we treat them as a function and call them using parenthesis, we get the TypeError: ‘float’ object is not callable Error.
In this Python tutorial, we will discuss this Python error and learn why it raises and how to solve it. We will also discuss some Python code snippet that causes this error and solve them so that you can have a better understanding of this error. So let’s get started with the error itself.
Python Error: TypeError: ‘float’ object is not callable
The Python Error TypeError: ‘float’ object is not callable is divided into two statements, Error Type and Error Message, separated with a colon : .
- Error Type ( TypeError ): TypeError is one of the most common Python standard exceptions, and it raises when we perform an incorrect operation on a Python object.
- Error Message( ‘float’ object is not callable ): This is the error message, which tells us that we are calling a Python float object as a function, which is invalid in Python.
Error Reason
Float objects are used in Python to store floating-point numbers, but if we call a float variable as a function by putting a parenthesis after its variable name, we receive the TypeError: ‘float’ object is not callable error.
Example
Output
Break the Code
In the above example, we are getting the error because when we put the parenthesis () after a variable name, Python treats it as a function calling statement. But in the above example, my_num it is not a function. It is a float number. That’s why Python threw the error ‘float’ object is not callable , which simply means we can not call the float objects functions.
Common Error Example
There are two common major cases when many new Python learners commit the mistake and encounter this error.
- Scenario 1: Used float as a variable name and used the float() function afterward.
- Scenario 2: Forget to put the math operator between the opening parenthesis and the float number.
Scenario 1 (Used float as a variable name)
The most common mistake that many new python learners do is when they use the float keywords as a variable name to store a floating-point number, and in the same program, they also use the float() function to convert an object to a floating-point object.
Example
Output
Break the Code
In the above example, we are trying to convert the user entered height in inches to feet. But we are receiving the TypeError: ‘float’ object is not callable error at line 4.
This is because, in line 2, we have defined a variable by name float whose value is 12.0 , that represents the value to convert the inches to feet. But, in line 4, we are using the Python float() function to convert the user input height to a floating-point number.
But now for Python float is not a function anymore. It is a floating-point variable whose value is 12.0. that is defined in line 2. By which it will not call the actual Python inbuilt function float(). Instead, it will call the float variable a function, which will lead to the TypeError: ‘float’ object is not callable error.
Solution
The solution for the above scenario is very simple. All we need to do is change the name of the float variable to something else. This is also very important. While we want to write good code in Python, we never use keywords and function names to define a variable.
Solution 1
Output
Scenario 2 (Forget to put the math operator )
In mathematics, if we do not put any operator between the number and the opening parenthesis (, then we treat that expression as a multiplication symbol between the number outside the parenthesis and the number inside the parenthesis.
For instance(in mathematics)
But in Python programming, we need to specify the Arithmetic operator between the number and the opening or closing parenthesis; else, we get the error.
for instance (in python)
Example
Output
Break the code
If we look at the error code statement, we can see that the error occurred on line 7 with the result = a(b+c) statement. This is because we forget to put the * operator after variable a . The Python interpreter mishandles the floating-point variable a with the function calling statement.
Solution
The solution to this problem is also very straightforward. All we need to do is place the Arithmetic operator between variable a and ( parenthesis.
solution 2
Output
Conclusion
In this Python tutorial, we learned what is TypeError: ‘float’ object is not callable error in Python and how to solve it. If we look closely at the error message, we can tell that the error is related to the float and calling a function. The only reason this error occurs is when we write a function calling statement using a Python floating-point variable or value.
If you have a basic knowledge of Python floats and functions, debugging this error would be a piece of cake for you. If you are still getting this error in your Python program, you can share your code in the comment section. We will be happy to help you in debugging.
