Function Returns None

After making an error then doing recursion i get None. def getplayerinput(): a = ['rock','paper','scissors'] plin = raw_input('Choose %s/%s/%s: ' %(a[0], a[1], a[2])) p

Solution 1:

You do not return anything once the input is not valid. Do this instead:

def getplayerinput():
    a = ["rock","paper","scissors"]
    plin = raw_input("Choose %s/%s/%s: " %(a[0], a[1], a[2]))
    print plin,'-first print'if plin not in a:
        print"Wrong input"return getplayerinput() # <- added returnelse:
        print plin,'-second print'return plin

for i in range(0,11):
    print getplayerinput()

Otherwise the recursion call will return something to a top level call, but that one just swallows the return value from the recursion call, since it doesn't pass it on via return.
