提示:接收游戏者的选择,并且与计算机的选择进行比较。计算机的选择是从选择列表中随机选取的。如果游戏者获胜,则增加1分。
import random
choices = ["Rock", "Paper", "Scissors"]
computer = random.choice(choices)
player = False
cpu_score = 0
player_score = 0
while True:
player = input("Rock, Paper or Scissors?").capitalize()
# 判断游戏者和电脑的选择
if player == computer:
print("Tie!")
elif player == "Rock":
if computer == "Paper":
print("You lose!", computer, "covers", player)
cpu_score+=1
else:
print("You win!", player, "smashes", computer)
player_score+=1
elif player == "Paper":
if computer == "Scissors":
print("You lose!", computer, "cut", player)
cpu_score+=1
else:
print("You win!", player, "covers", computer)
player_score+=1
elif player == "Scissors":
if computer == "Rock":
print("You lose...", computer, "smashes", player)
cpu_score+=1
else:
print("You win!", player, "cut", computer)
player_score+=1
elif player=='E':

以上就是今天分享的内容。
项目中有些需要适当调整。比如自动发送邮件,可以选择使用QQ邮箱;查询天气信息也可使用国内一些免费的API;维基百科可以对应百度百科;谷歌搜索可以对应百度搜索等等。
这些都是大伙在运行过程中需要注意的。
