Program 1


Version 1


An elegant solution that simply replicates the code for each round. We hadn't seen the while loop yet, so this was perfectly acceptable. The code is well organized and easy to scan/read.

# hw3a.py
# by Zoey Jingyi Sun(ch) and Phyllis Chen(cv)
# (slightly edited by D. Thiebaut)
#
# This program allow users to play a more advanced version of
# "ROCK/PAPER/SCISSORS/MUG" by adding a MUG option. The rules are "Scissors fall in mug, and mug wins
#  Paper blocks mug, and paper wins,Rock breaks mug, and rock wins". This program
#  will let the user play three rounds and keep track of the score. In the end, it
#  will declare the winner.
# 

#Initialized the computerscore and humanscore
computerScore = 0
humanScore = 0

Version 2


Here we have a solution where a while loop is used. Notice how much tighter the code is when we use loops! The code is well documented and comments highlights the different sections.

# choice, recognizes both lowercase and uppercase inputs from the user, lets
# the user play 3 rounds with the computer, keeps track of the score, and
# prints the result for each round and for each 3-round game.


from random import choice

OPTIONS = ['R', 'P', 'S', 'M' ]
NOROUNDS = 3

# Create/initialize the variables which will keep track of the score
computerScore = 0
humanScore = 0

# =============================================

# After 3 rounds, the result of the entire game will be printed
round = 0
while round < NOROUNDS:

    computer = choice( OPTIONS )
    human = input( "What is your choice?\n" ).upper()
    print( "The computer has chosen", computer )
    if ( computer=='R' and human=='P' ) \

       or ( computer=='M' and human=='R' ) :
        print( "YOU WIN!" )
        humanScore = humanScore + 1

       or ( computer=='R' and human=='M' ) :
        print( "YOU LOSE" )
        computerScore = computerScore + 1
    else:
        print( "It's a tie!" )
    round = round + 1       

# =============================================
