from a import b assigns the variable named b to the imported object, so you're overshadowing the built-in exit.

You can also just print out a string representation of exit to see this. Run

print(exit, type(exit))
from sys import exit
print(exit, type(exit))

to see:

(Use exit() or Ctrl-D (i.e. EOF) to exit, <class 'site.Quitter'>)
(<built-in function exit>, <type 'builtin_function_or_method'>)

Of course, there is rarely a reason to overshadow a built-in. Why not

import sys
sys.exit()

instead?
