Hmm, my while loop with or doesn't seem to work as I want it to...
How do I tell the while loop to only accept Y or y or N or n
input from the str(raw_input)?
Thank's in advance!
Snippet of code:
import os
def buildfinder():
os.system(CLS)
GameRoot = os.getenv(GAME_ROOT) + \\
while usrinp != y or Y or N or n: PROBLEM
Correct way:
while usrinp != y or usrinp != Y or usrinp != N or usrinp != n:
There has to be a boolean evaluation on both sides of or.
Or in this case:
while usrinp not in ['Y', 'y', 'N', 'n']:

But note that 'in' performs a substring search and therefore yn and

Oh right, that's a recent change to the language, I think. OK:
while not usrinp.lower() in list(yn): ...
