python - 石头剪刀布游戏，无限循环

Question

import random

options = ['Rock','Paper', 'Scissor']
npc = random.choice(options)

print('Hello')
print('We are about to play Rock,Paper,Scissors.')

while True:
  npc = random.choice(options)
  player = str(input('Please declare your weapon: ')).capitalize()
  if (player == npc):
    print('Your choice: ', player)
    print('npc choice: ', npc)
    print('Oopsie looks like we have a tie!')
    print('Lets Try again!')
    continue
  if (player != 'Rock') or (player != 'Paper') or (player != 'Scissor'):
    print('Poo Poo, that is not a valid option! Please try again!')
    continue
  if ((player == 'Rock') and (npc == 'Scissor')) or ((player == 'Scissor') and (npc == 'Paper')) or ((player == 'Paper') and (npc == 'Rock')):
    print('Your choice: ', player)
    print('npc choice: ', npc)
    print('You win!')
    break
  if ((player == 'Rock') and (npc == 'Paper')) or ((player == 'Scissor') and (npc == 'Rock')) or ((player == 'Paper') and (npc == 'Scissor')):
    print('Your choice: ', player)
    print('npc choice: ', npc)
    print('You lose!')
    break

它一直打印出 it's a Tie 并且不会显示任何其他结果。我刚刚开始编程。任何输入将不胜感激!

编辑:循环已解决。

这是根据请求的示例输出:

   Output: Hello
           We are about to play Rock,Paper,Scissors.
           Please declare your weapon: rock
           Your choice:  Rock
           npc choice:  Paper
           You lose!

Answer 1

这一行

if (player != 'Rock') or (player != 'Paper') or (player != 'Scissor'):

如果没有领带，

将始终为 True。改成

if player not in options:

改进代码的一些建议

您可以删除所有 if 中的 ()。这个

if (player == npc):

与

相同

if player == npc:

您还应该使用 if/elif/else 而不是仅使用 if。这将使 continue 的使用变得不必要。

编辑:改进版本:

import random

options = ['Rock','Paper', 'Scissor']
npc = random.choice(options)

print('Hello')
print('We are about to play Rock,Paper,Scissors.')

while True:
  npc = random.choice(options)
  player = str(input('Please declare your weapon: ')).capitalize()
  if player == npc:
    print('Your choice: ', player)
    print('npc choice: ', npc)
    print('Oopsie looks like we have a tie!')
    print('Lets Try again!')
  elif player not in options:
    print('Poo Poo, that is not a valid option! Please try again!')
  elif (player == 'Rock' and npc == 'Scissor') or (player == 'Scissor' and npc == 'Paper') or (player == 'Paper' and npc == 'Rock'):
    print('Your choice: ', player)
    print('npc choice: ', npc)
    print('You win!')
    break
  else:
    print('Your choice: ', player)
    print('npc choice: ', npc)
    print('You lose!')
    break
