There are different types of errors in Python like keyError, AttributeError, SyntaxError, NameError, etc. There is one more error that is most common is TypeError. The main cause of this error is when trying some operation on a datatype and that particular operation is not applicable on that specific datatype. Here, we are going to highlight a TypeError in python ‘TypeError: ‘int’ object is not callable’.

How to Fix TypeError: ‘int’ object is not callable

The root causes of TypeError: ‘int’ object is not callable are

• Same name for int function and variable
• Missing Arithmetic operator
• Parenthesis after a number

Checkout each root cause with the example and solution

Using the same name for int function and variable

This one is the most common mistake that most Python learners make when designing a program. For example, you want to determine the total sum of a bill list, and you use a built-in function of Python ‘sum()’ to calculate the sum list and then use the same name as the variable name.

This is exactly when you encounter TypeError: ‘int’ object is not callable

Code Example

bill = [28, 22, 29, 88, 89, 15, 18]

# total integer sum
sum = 0

# using the inbuilt Python sum method
sum = sum(bill)
print("The total bill is: ",sum)

Error message

Traceback (most recent call last):
File "main.py", line 7, in <module>
sum = sum(bill)
TypeError: 'int' object is not callable

Here, a new int variable is defined by the name sum=0, the Python program treats the sum as an int. At the same time, we also use sum as a function to calculate the sum of the bill, which makes the Python confused with the names. And, as a result, Python treats sum as an int object instead of a built-in function, so it returns TypeError: 'int' object is not callable.

Solution

Just change the int name

bill = [28, 22, 29, 88, 89, 15, 18]

# total integer
result = 0

# using the inbuilt Python sum method
result = sum(bill)

print("The total bill is: ",result)

Output

The total bill is: 289

Missing Arithmetic Operator

The absence of an arithmetic operation in an equation causes the error

Code Example

prices = [100,150,200,250,330]
discount = 20
sumPrice = sum(prices)
discountAmount = sumPrice(discount/100)
print("Total discount amount: ", discountAmount)

Error message

File "C:\Users\Admin\.spyder-py3\temp.py", line 4, in <module>
discountAmount = sumPrice(discount/100)
TypeError: 'int' object is not callable

Missing an operator in the discountAmount causes the error

Solution

prices = [100,150,200,250,330]
discount = 20
sumPrice = sum(prices)
discountAmount = sumPrice*(discount/100)
print("Total discount amount: ", discountAmount)

Output

Total discount amount:  206.0

Parenthesis Placement After an Int

Using parenthesis exactly after an integer leads to an error. Denote the right operator instead of just bracketing the raw integer.

Code Example

99(999)

Error message

File "C:\Users\Admin\.spyder-py3\temp.py", line 2, in <module>
99(999)
TypeError: 'int' object is not callable

Solution

99 * 999

Conclusion

We shed light on the exception TypeError: ‘int’ object is not callable and how to tackle it. Basic flaws in the code can lead to this error. It’s time to complete your project where you have been witnessing this TyprError.
