[Affinity]

Full program:

import random

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

def get_choices():
    player_choice = input("Enter a choice of rock, paper, or scissors: ")
    computer_choice = random.choice(moves)

    choices = {"player": player_choice, "computer": computer_choice}

    return choices 

def check_win(player, computer):
    print("You chose " + player + " and the computer chose " + computer)
    if player == computer:  
        return "It's a tie"
    
    elif player == "rock":
        if computer == "scissors":
            return "Rock beats scissors"
        else:
            return "Paper beats rock"
        
    elif player == "paper":
        if computer == "rock":
            return "Paper beasts rock"
        else:
            return "Scissors beats paper"
        
    elif player == "scissors":
        if computer == "paper":
            return "Scissors beats paper"
        else:
            return "Rocks beats scissors"
    
    
choices = get_choices()

results = check_win(choices["player"],choices["computer"])

print(results)
