How to exit a program in Python?

Question

I want to exit the program if a condition is false.
How can I do that?

Answer 1

while not condition:

There, if the condition was true before the loop and it becomes false, the loop will break

You could also do

while True:
if condition == False: break

You can also make the program in a function, and use a return statement to break out.

from sys import exit
if CRAP!!:
exit()
