Rock, Paper, Scissors, Shoot Python Coding Game

June 28, 2022

In this activity, you will create an RPS game that takes user input from the command line and plays against the computer.

Starter file

# Incorporate the random library
import random

# Print Title
print("Let's Play Rock Paper Scissors!")

# Specify the three options
options = ["r", "p", "s"]

# Computer Selection
computer_choice = random.choice(options)

# User Selection
user_choice = input("Make your Choice: (r)ock, (p)aper, (s)cissors? ")

# Run Conditionals

Instructions

1. Using the command line, take an input of r, p, or s, which stands for rock, paper, and scissors.
2. Have the computer randomly choose one of these three choices.
3. Compare the user’s input to the computer’s choice to determine if the user won, lost, or tied.
4. Remember to pseudo-code first!

Hint

You can refer to this Stack Overflow post for help with performing random selections in Python.

Solution

# Specify the three options
options = ["r", "p", "s"]

# Computer Selection
computer_choice = random.choice(options)

# User Selection
user_choice = input("Make your Choice: (r)ock, (p)aper, (s)cissors? ")

# Run Conditionals
if (user_choice == "r" and computer_choice == "p"):
    print("You chose rock. The computer chose paper.")
    print("Sorry. You lose.")

elif (user_choice == "r" and computer_choice == "s"):
    print("You chose rock. The computer chose scissors.")
    print("Yay! You won.")

elif (user_choice == "r" and computer_choice == "r"):
    print("You chose rock. The computer chose rock.")
    print("A smashing tie!")

elif (user_choice == "p" and computer_choice == "p"):
    print("You chose paper. The computer chose paper.")
    print("A smashing tie!")

elif (user_choice == "p" and computer_choice == "s"):

    print("A smashing tie!")

elif (user_choice == "s" and computer_choice == "r"):
    print("You chose scissors. The computer chose rock.")
    print("Sorry. You lose.")

else:
    print("I don't understand that!")
    print("Next time, choose from 'r', 'p', or 's'.")
