Great code, here is is tutorial to make fruit ninja game in python

@basket random Thank you for providing the useful code.

If Player 1 puts a lowercase x by accident, then it makes both players "x". Maybe put that in parentheses in the input statement preceding that option, or while loop to restrict input?

Very nice code btw

here is my version way shorter
