Python - Rock, Paper, Scissors (while loops and conditionals)

[JeremiahSandusky]

Thanks for the video! Im having issues with a project im working on. My instructor wants me to use a 'while' loop to force the player to try again if they choose anything but rock, paper, or scissors. But when i add a while loop to the function it gives me errors. Any input as how i would get that to work? Thank you.
