python - paper rock scissor - Global Variable? -


why not working? need assign global variables? it's saying player1 not defined!

options=["p", "s", "r"]  def valid1():     validationa = true     while validationa==true:         player1=input("player 1.. take go")         if player1 not in options:             print ("invalid")         else:             validationa==false             return player1  def valid2():     validationb = true     while validationb==true:         player2=input("player 2.. take go")         if player2 not in options:             print ("invalid")         else:             validationb==false             return player2 valid1() valid2()  if player1=="p" , player2 =="p":     print("draw") else:     print("works unfinished")

your functions return values, never assign them anything.

player1 = valid1() player2 = valid2()

in fact, these functions exact same thing, if make text either dynamic or more generic have single function , call twice

player1 = valid() player2 = valid()
