TypeError: Object is Not Callable
TypeError: 'int' object is not callableQuick Answer
You are trying to call a non-callable object like an integer or list as if it were a function. This usually happens when you shadow a built-in name with a variable. Rename your variable to avoid conflicting with built-in names.
Why This Happens
Python allows you to reassign built-in names like list, str, int, or len to regular values. Once you do, the original built-in is shadowed in that scope. When you later try to call the built-in, Python finds your variable instead and tries to call it, raising TypeError.
The Problem
sum = 100
total = sum([1, 2, 3]) # 'int' object is not callableThe Fix
total_value = 100
total = sum([1, 2, 3]) # Works fineStep-by-Step Fix
- 1
Find the shadowed name
Search your code for any variable assignment that uses a built-in name like list, dict, sum, type, id, or input.
- 2
Rename the variable
Change the variable name to something descriptive that does not conflict with Python built-ins.
- 3
Restart your REPL if needed
If you are in an interactive session, the shadowed name persists. Restart or use del to remove the binding.
