Using OR in Python for a yes/no?

Question

I\'m wanting to have a \"y/n\" in Python, which i\'ve successfully done, but I want the user to be able to input a \"y\" or a \"Y\" and it accepts both.

Here\'s a short

Answer 1

It is or as in

if yn == 'y' or yn == 'Y':.

Although a better method would be

if yn in ['y', 'Y']:

or

if yn.lower() == 'y':.

Answer 2

You're looking for

if yn in ("y", "Y"):

Or better:

if yn.lower() == 'y':

Answer 3

if yn in "yY":

is more succinct than

if yn in ['y', 'Y']:

or similar statements. It works because a string is a sequence in Python, just like a list or tuple.

It would evaluate to True if the user enters literally "yY", though.

Answer 4

choose:

if yn in ["y","Y"]:
    break

if yn.lower() == "y":
    break
