关于程序相关的

您可以反复玩游戏,直到选择停止为止。

该程序跟踪获胜情况。

大小写无关紧要(即ROCK与Rock相同)。

如果您输入的内容无效,程序会一直提示您,直到您输入有效的内容。

对项目进行编码的步骤:

创建一个简单的单轮游戏版本,我们不执行正确的输入。

如果输入了无效的内容,则添加while循环可重新提示用户输入选择。

使用while循环让用户反复播放,并使用变量来跟踪得分。

程序代码

import random

input("Welcome to Rock, Paper, Scissors! Press Enter to start.")

print()

user_wins = 0

computer_wins = 0

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

while True:

random_index = random.randint(0,2)

cpu_choice = choices[random_index]

user_choice = input("Rock, Paper, or Scissors? ").lower()

while user_choice not in choices:

user_choice = input("That is not a valid choice. Please try again: ").lower()

print()

print("Your choice:", user_choice)

print("Computer's choice:", cpu_choice)

print()

if user_choice == 'rock':

if cpu_choice == 'rock':

print("It's a tie!")

elif cpu_choice == 'scissors':

print("You win!")

user_wins+=1

elif cpu_choice == 'paper':

print("You lose!")

computer_wins+=1

elif user_choice == 'paper':

if cpu_choice == 'paper':

print("It's a tie!")

elif cpu_choice == 'rock':

print("You win!")

user_wins+=1

elif cpu_choice == 'scissors':

print("You lose!")

computer_wins+=1

elif user_choice == 'scissors':

if cpu_choice == 'scissors':

print("It's a tie!")

elif cpu_choice == 'paper':

print("You win!")

user_wins+=1

elif cpu_choice == 'rock':

print("You lose!")

computer_wins+=1

print()

print("You have "+str(user_wins)+" wins")

print("The computer has "+str(computer_wins)+" wins")

print()

repeat = input("Play again? (Y/N) ").lower()

while repeat not in ['y', 'n']:

repeat = input("That is not a valid choice. Please try again: ").lower()

if repeat == 'n':

break

print("\n----------------------------\n")

运行效果:
