In Python, curly brackets have a specific purpose. They serve as a symbol for a function call. Python will assume you are attempting to call a function if you supply a pair of curly braces after a number without placing an operator in between them. The message “TypeError: ‘int’ object is not callable” will appear as a result. This guide discusses the significance of this inaccuracy and the causes of it. To assist you in identifying the cause of the mistake in your code, we walk over a few examples of this error.
TypeError: ‘int’ object is not callable
Curly brackets are used to invoke Python functions. Consider the following function call statement:
This function takes two arguments. The parameters we specified are 5 and 10. Since curly brackets have this unique meaning, they cannot be used to refer to an integer.
The two most prevalent scenarios in which developers attempt to call an integer are:
- The integer value of a function that has been reassigned
- A missing math operator in a computation
Let’s analyze each instance one by one to assist you address the mistake you’re facing.
Method 1: Function Has an Integer Value
myNums = [56,13,21,54] sum = 0 sum = sum(myNums) print("sum of myNums list: ", sum)
Output and explanation
- Four integers are list in the variable myNums.
- Initializing a variable Sum with a value of 0
- With the help of the sum() function, the sum of the myNums list is determined and placed in the sum variable.
- It prints the results.
What took place here? Step 2 involves setting a variable named sum to zero. Sum is a predefined function in Python. Next, step 3 attempt to utilize the sum function is unsuccessful. Since step 2, Python just keeps track of the total as a variable. Sum() is now completely useless because it was declared a variable.
We can use more evocative variable names that are not preset in place of sum as a variable declaration, such as mySum, mySum, and totalSum. Be careful to adhere to PEP 8’s naming convention.
myNums = [56,13,21,54] totalSum = 0 totalSum= sum(myNums) print("sum of myNums list: ", totalSum)
sum of myNums list: 144
Method 2: Missing a Mathematical Operator
Arithmetic operators are not provided when calculating integers
Equations without arithmetic operators may throw a TypeError: object “int” is not callable. Observe the example below:
prices = [44,54,24,67] tax = 10 totalPrice = sum(prices) taxAmount = totalPrice(tax/100) print("total taxable amounr: ", taxAmount)
Output and Explanation
File "C:\Users\Admin\.spyder-py3\temp.py", line 4, in <module> taxAmount = totalPrice(tax/100) TypeError: 'int' object is not callable
- A collection of integers kept in variableprices
- The tax rate is fix at 10%.
- The totalPrice variable computes and stores the total price.
- Determine the whole taxable amount.
- The outcome is printed.
We must multiply totalPrice by the tax % in order to determine the taxable amount. The * operator is absent while computing taxAmount in step 4. Hence, TypeError is raised: There Is No Callable “int” Object
All operators must be stated unambiguously.
prices = [44,54,24,67] tax = 10 totalPrice = sum(prices) taxAmount = totalPrice*(tax/100) print("total taxable amounr: ", taxAmount)
total taxable amount: 18.900000000000002
Add parenthesis after an integer
1 ( 2 )
Output and Explanation
File "C:\Users\Admin\.spyder-py3\temp.py", line 2, in <module> 1(2) TypeError: 'int' object is not callable
Parentheses should never be placed after a number, according to syntax. It’s crucial to confirm the operators are proper, just like in the prior section.
After an integer, no brackets are allowed. Display the proper operators.

When you attempt to call an integer, the message “TypeError: ‘int’ object is not callable” is shown. If you neglect to add an operator in the computation, this may occur. Using the built-in function name as a variable identifier and, where required, defining arithmetic signs can help you avoid mistakes.
