Learning Python: developing Rock, Paper, Scissors game in 15 min.

import random

#Step 2: implement the random
comp = random.randrange(1,4)
user = random.randrange(1,4)

#Step 3: assigning the integer to Rock, Scissor and Paper before the next block
if comp == 1:
  comp = 'paper'
elif comp == 2:
  comp = 'rock'
elif comp == 3:
  comp = 'scissor'

if user == 1:
  user = 'paper'
elif user == 2:
  user = 'rock'
elif user == 3:
  user = 'rock'

print "Computer choose: ",comp
print "User choose:     ", user

print ""

#Step 1: build the main logic of the RSP
"""4 possibilities, if comp is rock, how user win the game and so on"""

if comp == user:
  print 'Tie !!!'
elif comp == 'rock':
  if user == 'paper':
    print 'User win !'
  else:
      print 'Computer win !'
elif comp == 'paper':
  if user == 'scissor':
    print 'User win !'
  else:
    print 'Computer win !'
elif comp == 'scissor':
  if user == 'rock':
    print 'User win !'
  else:
    print 'Computer win !'

Output

Computer choose:  rock
User choose:      rock

Tie !!!
