Because exit might be a variable you use to determine if you should exit. exit() is a function that actually does the exiting.

It’s the difference between pointing at a jogger and saying “run” and actually running after them.

If you have a variable called exit you've overwritten the function in that scope, and won't be able to execute it.

e.g.

>>> exit=1
>>> exit()
Traceback (most recent call last):
  File "", line 1, in 
TypeError: 'int' object is not callable
>>>
