while int(input( 'Press 1 to roll the dice or 0 to exit:\n')): print(random.randint(1,6))
--------------------------------------------------------------------
Press 1 to roll the dice or e to exit
② 石头剪刀布游戏

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':
print("Final Scores:")
print(f"CPU:{cpu_score}")
print(f"Plaer:{player_score}")
break
else:
print("That's not a valid play. Check your spelling!")
computer = random.choice(choices)
③ 随机密码生成器
