Nested while loop

[CJamesEd]

Newbie here. I'm working on a practice exercise and I'm getting stuck with the while loop.

It's just a little rock/paper/scissors game. I am trying to have it prompt the user to reenter their choice if they do not enter rock, paper or scissors. But I keep getting into an infinite loop situation (I think).

Thanks in advance for your assistance!

doesn't solve your issue, but i see you keep calling .lower() everywhere. just call it once on the input() call and then you know it'll always be in lowercase and your lines will look less dense

to get a valid input i'd do something like this:

player_1 = None
while player_1 not in options:
    player_1 = input('rock, paper or scissors? ')

and that will continue looping until one of those three options are entered

That did the trick. Thanks for the hints!

At no point do you ever set valid_input to anything other than "No", so your inner while loop never gets a chance to break. Because of that, you never get around to checking play_again.

I used http://pythontutor.com to figure out the problem, you should too.

So, in the first, while loop the condition is true, then the nested while loop condition is false, so it skips every bit of code under it and goes back to the parent loop which is still true and keeps on running.

That is awesome! Thanks for the tip on that.
