I have got as far as being able to input 'paper', 'scissors' or 'stone'. It's then that I get an error message saying that whatever I have inputed is "undefined". Here's my code:

[#the computer will select a random number from 1 to 3
#first the draws ...
#then the player wins ...
#then the computer wins ...
#then invalid entries
#then use up one round

while rounds != rounds_required:
    mighty = random.randint(1, 3)
    choice = input("What'sss your choisssce? ")
    if choice == "paper" and mighty == 1 or choice == "scissors" and mighty == 2 or choice == "stone" and mighty == 3:
        print "Amazzzingly you and the Mighty Python think alike ... "
        rounds = rounds + 1
    elif choice == "scissors" and mighty == 1:
        print "Aaah, your scissorsss cut my Mighty paper !!"
        player = player + 1
        rounds = rounds + 1
    elif choice == "stone" and mighty == 2:
        print "Youch, your pesssky ssstone blunted my Mighty ssscissorsss !!"
        player = player + 1
        rounds = rounds + 1
    elif choice == "paper" and mighty == 3:
        print "Hisss ... my Mighty ssstone wasss wrapped by your creepy paper !!"
        player = player + 1
        rounds = rounds + 1
    elif choice == "scissors" and mighty == 3 or choice == "paper" and mighty == 1 or choice == "stone" and mighty == 2:
        print "Hah! The Mighty Python triumphsss!!!"
        python = python + 1
        rounds = rounds + 1
    else:
        print "Invalid attempt ... please type all lower cassse and check your ssspelling."

#announce the final scores

if player == python:
    print "You were a worthy challenger we both scored", player," the true winner wasss the game."
elif player > python:
    print "I sssalute your random cunning you beat me by", player, " pointsss to", python, "."
else:
    print "The Mighty Python triumphsss by", python, " points to a mere", player, "pointsss!"]

I thought it might be the way I have herded together all those "and" and "or" commands but I rewrote it as 9 different elifs and got the same outcome. Of course that doesn't necessarily mean that the "and"s and "or"s are any good themselves does it?

I notice that you do this condition...

if player == python:

After you enter in a value into choice and it goes into one of the first if/elif statements, it won't set a value for python. It will skip over the condition where you set the python variable up. Thus you would be comparing player to a variable that doesn't exist (aka undefined).

See if that is what is happening. To fix it, you will need to setup the python variable before the while loop to some default value. Or make sure that no matter what if/elif it goes into, python gets set to something.

Hopefully that is what is wrong and it fixes it. />

Thanks for the suggestion - you are right. The only problem is that, accidently, I didn't attach the first part of my code which was:
[#paper, scissors, stone
#1 = paper, 2 = scissors, 3 = stone
#set the base number of rounds
#set the base score for the player and the computer

import random

rounds = 0
player = 0
python = 0

#issue the computer's challenge
#ask how many rounds the user wants to play

print """Thisss isss the Mighty Python talking ...
You are challenged to a contessst of random cunning ...
The game isss called - Paper, Ssscissorsss, Ssstone ..."""
rounds_required = int(raw_input ("How many rounds are you brave enough to play? "))

#create a loop for the rounds until the chosen number of rounds has been reached]

You are using python 2.7 (as indicated by the print statements) but you used input.
You need to use raw_input instead.

Change the line where you define your choice variable to this:

choice = raw_input("What'sss your choisssce? ")

Thanks Mekire - that was the problem. When you pointed it out I could not believe that I hadn't used raw_input until I looked back at my code. You have saved my muchos grief.

#Rock Paper Scissors Game
from random import randint


chose = ["rock","paper","scissors"]

result = [[["Draw Try Again."],["Paper Covers Rock -- Human Wins"],["Rock Smashes Scissors -- Computer Wins"]],[["Paper Covers Rock -- Computer Wins"],["Draw Try Again"],["Scissors Cut Paper -- Human Wins"]],[["Rock Smashes Scissors -- Human Wins"],["Scissors Cut Paper -- Computer Wins"],["Draw Try Again"]]]

player = int(raw_input("Rock <0> Paper <1> Scissors <2>"))

computer = randint(0,2)



print "Player chose ",chose[player]," and computer chose ",chose[computer]

print result[computer][player]    

Just thought id say there is a better way to solve this problem. When you look at my code you will see that ive taken advantage of how the code repeats and put it all into a list for easy retrieval instead of using many complicated if thens. Also if you want to make this code repeat games just put the body into a while loop with and exit statement when the player wants to quit.

Also if you want to attach this to a GUI then all you have to do is call the library and then past this into the main loop and put the player responses into a text box or use a frame to do an animation.

Anyway i thought id show you an easy way to achieve the result you want.

Hope you like this.
