[Solved] Python While Statements

Okay, well generally you might do something like this

def confirm_with_user():
    user_data = ""
    while user_data not in "YyYesNnNo":
        user_data = input("Are you sure? (Y/N) ")

    return user_data.lower() in "yes":

Then at the point in your code when you want to confirm with your user you just do

if confirm_with_user():
    #proceed...
else:
    #They don't want to proceed
