我正在研究一种石头剪刀游戏。除了赢/输/领带计数器之外，一切似乎都运转良好。我看过人们在这里发布的其他一些游戏，我仍然无法让我的工作。我觉得我太近了，但我无法得到它！谢谢你的帮助。这是我第一次在这里发帖，所以如果我搞砸了格式，我很抱歉。
我编辑了代码，但仍然无法让程序在不使用全局变量的情况下识别计数器。在我的编辑的一个点上，我设法让它把所有东西都算作一个平局...我不知道怎么样，我在编辑的某个地方丢了它。大声笑。 - 再次感谢所有人！
这是我运行程序时得到的结果：

to the object you want to choose.
Select rock(1), paper(2), or scissors(3): 1
Computer chose PAPER .
You chose ROCK .
You lose!
Play again? Enter 'y' for yes or 'n' for no. y

你的winner_result函数在递增win计数器之前返回。如果从中删除所有return语句，则应更新计数器。无论如何都不需要return语句，因为if/elif/else结构确保只执行一个可能的结果。
正如Junuxx在评论中所说，您还需要正确地为winner_result变量分配值，即winner_result = 'win'而不是winner_result == 'win'。我还要重命名winner_result变量或函数，因为两者都使用相同的名称会令人困惑。
win/lose/tie变量目前是本地变量，这意味着main和winner_result将拥有这些变量的副本，因此main的值始终为零。你可以做的是使它们成为全局变量：在全局范围内（在任何函数之外）将它们分配为零，并在函数global win, lose, tie中添加行winner_result。

很明显，自从这个问题被回答以来已经过了好几年了，但是当我寻找相同的信息时却出现了。如果有人感兴趣，这是我的代码。
#! usr/bin/python3
import random
def game():
computer_count = 0
user_count = 0
while True:
base_choice = ['scissors', 'paper', 'rock']
computer_choice = random.choice(base_choice)
user_choice = input('(scissors, paper, rock) Type your choice: ').strip().lower()
print()
computer_wins = 'The computer wins!'
you_win = 'You win!'
print(f'You played {user_choice}, the computer played {computer_choice}')
if user_choice == 'scissors' and computer_choice == 'rock' or \
user_choice == 'paper' and computer_choice == 'scissors' or \
user_choice == 'rock' and computer_choice == 'paper':
print(computer_wins)
computer_count += 1
elif user_choice == 'rock' and computer_choice == 'scissors' or \
user_choice == 'scissors' and computer_choice == 'paper' or \
user_choice == 'paper' and computer_choice == 'rock':
print(you_win)
user_count += 1
else:
if user_choice == computer_choice:
print('Its a draw!')
computer_count += 1
user_count += 1
print(f'Computer: {computer_count} - You: {user_count}')

我试图做同样的项目，但我找到了一个对我来说很好的解决方案。
