Code to close a python program?

Question

I'm beginner to python. I've learnt java there's one line to close/exit the program ('System.exit (0)'). I'm curious if there's any in python.

Answer 1

There's a module sys that allows the same technique:

from sys import exit
exit(0)

Answer 2

exit() does the trick (tested in SL and Pythonista).

Answer 3

It depends on the specific runtime if exit is available just like that.

There's also 'quit'.
