# import the random library so that the computer can choose randomly
import random

choices = ['rock', 'paper', 'scissors']
# ask the player to enter a choice and change it to all lowercase
player = input("Enter a choice " + str(choices) +": ").lower()
# randomly choose a value for the computer
comp = random.choice(choices)
# print the computer's choice
print("Computer:", comp)

# check if the player's choice is invalid (not in the list)
if player not in choices:
    print("Invalid choice:", player)

# check if the game ends in a tie
elif player == comp:

# check the other 2 combinations for when player chooses 'rock'
elif player == 'rock':
    # can nest if-statements inside of each other, just make sure spacing is correct
    if comp == 'paper':
        print("Paper covers Rock! You lose!")
    else: # comp == 'scissors'
        print("Rock crushes Scissors! You win!")
        
# do the last two conditions on your own!
