Rock, Paper, Scissors in Python I was eventually going to add another computer and more options to this (i.e., Rock-paper-scissors-lizard-Spock) but I wanted to make sure I was using the best practice for this type of game. Any help would be appreciated. 

# The traditional paper scissors rock game

import os
def clear():
    os.system("clear")
clear()
print ("\n\nPaper, Rock, Scissors Game -(Best of five games)")
x = 0 ;  l = 0 ;  w = 0 ; d = 0 ; lt = 0 ; wt = 0 ; dt = 0
while x &lt; 5:
  x = x + 1
  import random
  class Computer:
         pass
  comp_is = Computer()
  comp_is.opt = ('r','p','s')
  comp_is.rand = random.choice(comp_is.opt)

  if comp_is.rand == 'r':
            comp  = 'rock'
  elif comp_is.rand == 'p':
            comp  = 'paper'
  else:
        comp  = 'scissors'

  class Human:
       pass
  human_is = Human
  print
  human_is.player = raw_input(' Enter your choice of\n   r\
 for rock\n   p for paper or\n   s for scissors ... ')
  print

  class Result:
     pass
  Result_is = Result
  if comp_is.rand == human_is.player:
    print ("draw - computer chose ",  comp)
    print
    d = d + 1
    dt = dt + 1
  elif comp_is.rand == 'r' and human_is.player == 'p':
      print ("  player beats computer -computer chose ",  comp)

      print
      w = w + 1
      wt = wt + 1
  elif comp_is.rand == 'p' and human_is.player == 's':
      print ("  computer chose ",  comp)
      print ("  player beats computer-because scissors cuts paper")
      print ()
      w = w + 1
      wt = wt + 1
  elif comp_is.rand == 's' and human_is.player == 'r':
     print (" computer chose ", comp) 
     print (" player beats computer-because rock breaks scissors")
     w = w + 1
     wt = wt + 1
  else :
     print ("   computer wins - computer chose  ", comp)
     print

     lt = lt + 1

  if x == 5:

    print ()   
    print ("  games  won ... ",  w)
    print ("  games lost ... ",  l)

    print ()
    print ("  Running total overall of games won ... ", wt)
    print ("  Running total overall of games lost ... ", lt)
    print ("  Running total overall of games drawn ... ", dt)
    print ()
    w = 0 ; l = 0 ; d = 0
    again = input('Do you want to play again y for yes, n for no ..  ')
    if again == 'y':
       x = 0
    else:
      print

There is much to improve. I recommend you read PEP 8, the official Python style guide. It includes many important tips like:


Use consistent 4-space indentation
Multiple statements on the same line are discouraged


Furthermore:


You should use words instead of single letters for your variable names. All those variables like x, l, w, d, lt, wt, dt aren't self-explaining. What is their purpose? Instead: count_rounds, count_losses, count_wins, count_draws, ….
Your usage of object oriented features is extremely weird. Get rid of all classes for now.
Instead of x = x + 1 write x += 1.
Your code is really complicated because it munges together the user interface (prompting the user for choices, displaying results) with the actual logic of your program. Put the logic into separate functions, e.g.

def beats(choice_a, choice_b):
    if choice_a == 'rock' and choice_b == 'scissors':
        return 'smashes'
    if choice_a == 'scissors' and choice_b == 'paper':
        return 'cuts'
    if choice_a == 'paper' and choice_b == 'rock':
        return 'wraps'
    else:
        return None


This could be used as

def result_string(computer, player):
    verb = beats(computer, player)
    if verb:
        return "computer beats player because %s %s %s" % (computer, verb, player)
    verb = beats(player, computer)
    if verb:
        return "player beats computer because %s %s %s" % (player, verb, computer)
    return "draw"


which in turn could be used as print(result_string(computer_choice, player_choice)).


Please try to fix these issues and to clean up your code, then come back and ask a new question for a second round of review.
