The Computer's Turn! 🤖

Hi coder! 🤖 In Rock, Paper, Scissors, the COMPUTER needs to pick too! And it should be a surprise, just like a real opponent! 🎲

Let's teach the computer to choose!

print('I am the computer. Let me pick! 🤖')

A List of Choices 📋

First we make a list of the three choices. A list holds many items inside square brackets [ ]! 📋

choices = ['rock', 'paper', 'scissors']
print('My options:', choices)

Bring in random 📦

To pick randomly, we need the random toolbox again! Import it at the top. 📦

import random
print('Random toolbox loaded! 🧰')

random.choice Picks One 🎯

The tool random.choice grabs ONE item from a list at random! 🎯 Perfect for the computer!

import random
choices = ['rock', 'paper', 'scissors']
computer = random.choice(choices)
print('Computer picked', computer)

A Different Pick Each Time 🔄

Run this a few times! The computer's pick changes — sometimes rock, sometimes paper, sometimes scissors. 🔄

import random
choices = ['rock', 'paper', 'scissors']
print(random.choice(choices))
print(random.choice(choices))
print(random.choice(choices))

Show With an Emoji 🎨

Let's show the computer's pick with a fun emoji! We check which one it picked. 🎨

computer = 'rock'
if computer == 'rock':
    print('Computer chose ✊')
elif computer == 'paper':
    print('Computer chose ✋')
elif computer == 'scissors':
    print('Computer chose ✌️')

Keep It a Surprise! 🤫

In a real game, we let the player guess first, THEN reveal the computer's pick. Surprise makes it fun! 🤫

import random
choices = ['rock', 'paper', 'scissors']
computer = random.choice(choices)
print('I have made my choice... 🤫')

Player and Computer Both Pick 🤝

Let's get the player's choice AND the computer's choice together! 🤝 Now we have two picks to compare!

import random
choices = ['rock', 'paper', 'scissors']
player = input('Your pick: ')
computer = random.choice(choices)
print('You:', player, '| Computer:', computer)

The Big Reveal! 🎭

Drumroll please! 🥁 Reveal both picks with style and emojis! 🎭

player = 'rock'
computer = 'scissors'
print('🥁 You picked', player)
print('🥁 I picked', computer)

Computer Is Fair ⚖️

Because random.choice is random, the computer doesn't cheat! Every option has an equal chance. Totally fair! ⚖️

import random
choices = ['rock', 'paper', 'scissors']
computer = random.choice(choices)
print('Fair and square, I chose', computer, '🤖')

Computer Pick Pro! 🚀

Now the computer can make its own random choice! 🚀 Run it many times to see the surprise. Next we'll find out who WINS!

import random
choices = ['rock', 'paper', 'scissors']
computer = random.choice(choices)
print('Computer is ready with', computer, '! 🤖')
