Hello,

I am new Python (about 2 weeks) and need some help. I am making a rock paper
scissors game that a user can play with the computer by using a while loop
and if elif else statements. It needs to keep score of the amount of losses
and wins, and give the user the option to play again after each round. I've
tried so many different options and I don't know what else to try. My
problem is making the program loop back around when the user selects y(yes)
to play again and defining the variables at the beginning. Here's my
program:

import random
print"Welcome to Rock,Paper, Scissors! This is a game of chance; the
computer randomly picks one of three throws."
print""
print"Rock beats Scissors, but is beaten by Paper."
print"Scissors beat Paper, but are beaten by Rock."
print"Paper beats Rock, but is beaten by Scissors."
print""
print"r for Rock"
print"s for Scissors"
wins=0
loses=0
print"p for Paper"
player=raw_input("Please pick your throw: (r,s,p):")
computer= random.choice(['r','s','p'])
print "Computer throw:", computer
y="something"
play=y
while play==y:
    if player=='r':
        if computer== 'r':
            print "Tie! Throw again."
        elif computer=='s':
            print "You win! r beats s"
            wins=wins+1
        elif computer == 'p':
            print "You lose! p beats r"
            loses=loses+1
        else:
            pass
    elif player=='s':
        if computer== 's':
            print "Tie! Throw again."
        elif computer=='p':
            print "You win! s beats p"
            wins=wins+1
        elif computer == 'r':
            print "You lose! r beats s"
            loses=loses+1
        else:
            pass
    elif player=='p':
            if computer== 'p':
                print "Tie! Throw again."
            elif computer=='r':
                print "You win! p beats r"
                wins=wins+1
            elif computer == 's':
                print "You lose! s beats p"
                loses=loses+1
            else:
                pass
    else:
        print "Invalid entry"
    print""
    print"Game Summary"
    print"Wins:", wins
    print"Loses:",loses
    play=raw_input("Play again? y (yes) or n (no):"
print"Thanks for playing!"



Thanks!

Joey
