I want my Python code to accept both uppercase and lowercase input.

I've tried casefold, but with no luck. Any help?

advice =""
while advice !=("Yes"):
      print("Would you like some advice!")
      advice = input("Yes or No?    ")
print("Always listen to your IT Teacher!")

I would like the input to accept Yes and yes as user input.

    Did you mean something like: `while advice.upper() !=("YES"):` – Nir Alfasi Feb 09 '15 at 09:37

You could just make advice uppercase eg.:

while advice.upper() != "YES"

This way it doesn't matter if the user inputs lower or upper case (or a mix).

    I would do the same with `.lower()` and `"yes"`, but that is probably a matter of personal choice. – glglgl Feb 09 '15 at 09:40
  • True you could use lower() doesn't matter really. Personally if I'm using a string constant I like to make it all uppercase to show that it is a constant but that's just me. – I_Khanage Feb 09 '15 at 09:43
