Ok, so I have this code that is working, but does little to validate
user input and I don't quite yet understand that process yet.
so given the following function:
def buildmenu(menuchoices):
for i, option in enumerate(menuchoices, 1):
Interesting, I didn't know enume
Ok, so I have this code that is working, but does little to validate
user input and I don't quite yet understand that process yet.
so given the following function:

print('%s. %s' % (i, option))

I'd like to be able to just ask the question again, and re-validate
the new input or offer a "press q to quit" option
Thats what loops are for...

situation where validation fails, but the answer to the question is
required.
so far
