def multiChoiceQuestion(options: list):
while True:

for x in range(len(options)):

I created a template to ask a multi choice question in python. The loop will never reach it's end, since there is always a continue or a return statement. Is the while True condition appropriate for it?

    Side note: for x in len(options): will produce an error as Python doesn't allow iteration over an integer. 200_success's approach is the way to go here, but for future reference, use for x in range(len(options)): if you really need to loop a certain number of times. This takes the len(options) integer and creates an interable out of it.

The while True is fine, and is probably the best way to do it. However, the rest of the flow control is a bit clumsy. By rearranging a few statements, you can eliminate the continues.



PEP 8, the official Python style guide, recommends lowercase_with_underscores for function names unless you have a good reason to deviate.



The loop to print the numbered menu would be better written using enumerate(). Also, Python supports double-ended comparisons for validating that the answer is in range.



def multi_choice_question(options: list):
while True:
print("nEnter the number of your choice - ")
for i, option in enumerate(options, 1):
print('{0}. {1}'.format(i, option))
print("n")
try:
answer = int(input())
if 1 <= answer <= len(options):
return answer
print("That option does not exist! Try again!")
except ValueError:
print("Doesn't seem like a number! Try again!")

I think that 200_success already covered most points. I would however like to add an alternative idea for the printing part:



print("Enter the number of your choice -",
*(f'{i}. {opt}' for i, opt in enumerate(options, 1)),
sep='n', end='nn')


Explanation:
from the docs we see that following signature for the print function:



 print(*objects, sep=' ', end='n', file=sys.stdout, flush=False)


we can therefore print everything with a single print call instead of three individual ones. I leave it up to you which one you perceive easier to use.
