TypeError: 'int' object is not callable

I tried to use the built-in sum() function, but it failed because I accidentally overwrote it with a variable.

reproduce.py

sum = 10
sum(1, 2)

Error message

TypeError: 'int' object is not callable

fix.py

total_sum = 10

numbers = [1, 2]
print(sum(numbers))

I changed the variable name so it doesn't override the built-in function.
