Question

我正在用python做石头剪刀布游戏。在其中，用户以及计算机将获得3次机会。赢得回合的人将获得1分。每回合，积分增加到获胜者。

代码如下：

from random import choice
def stone_paper_scissor(): #g = guess
  print("Choose either of the following:")
  print("     stone, paper, scissor")
  for i in range(3):
    guess = ("stone", "paper", "scissor")# guess
    user_g = input('ENTER YOUR GUESS:')
    user_g.lower()
    comp_g = choice(guess) #computer"s guess
    comp = 0 # computer's score
    user = 0 # user's score
#-------------------------------------------------------------------------
      # when both parties guess are the same
    if comp_g == user_g:
        print( "--------------------------------------" )
        print( "IT'S A DRAW!" )
        print( "--------------------------------------" )
        break
#-------------------------------------------------------------------------
      # when computer chooses stone(guess[0])
    if comp_g == guess[0]:
         if user_g == guess[1]:
               print( "----------------------------------" )
               print( "YOU WIN!" )
               print( "----------------------------------" )
               print("COMPUTER"+ comp_g)
               print("USER"+ user_g)
               user += 1
               print("USER: %d" %(user))
               print("COMPUTER: %d" %(comp))
         elif user_g == guess[2]:
               print( "----------------------------------" )
               print( "YOU LOSE!" )
               print( "----------------------------------" )
               print("COMPUTER"+ comp_g)
               print("USER"+ user_g)
               comp += 1
               print("USER: %d" %(user))
               print("COMPUTER: %d" %(comp))
#-------------------------------------------------------------------------
      # when computer chooses paper(guess[1])
    if comp_g == guess[1]:
         if user_g == guess[0]:
               print( "----------------------------------" )
               print( "YOU LOSE!" )
               print( "----------------------------------" )
               print("COMPUTER"+ comp_g)
               print("USER"+ user_g)
               comp += 1
               print("USER: %d" %(user))
               print("COMPUTER: %d" %(comp))
         elif user_g == guess[2]:
               print( "----------------------------------" )
               print( "YOU WIN!" )
               print( "----------------------------------" )
               print("COMPUTER" + comp_g)
               print("USER" + user_g)
               user += 1
               print("USER:  %d" %(user))
               print("COMPUTER: %d" %(comp))
#---------------------------------------------------------------------------
      # when computer chooses scissor (guess[2])
    if comp_g == guess[2]:
         if user_g ==  guess[0]:
               print( "----------------------------------" )
               print( "YOU WIN!" )
               print( "----------------------------------" )
               print("COMPUTER"+ comp_g)
               print("USER"+ user_g)
               user += 1
               print("USER:  %d" %(user))
               print("COMPUTER:  %d" %(comp))
         elif user_g == guess[1]:
               print( "----------------------------------" )
               print( "YOU LOSE!" )
               print( "----------------------------------" )
               print("COMPUTER"+ comp_g)
               print("USER"+ user_g)
               comp += 1
               print("USER: %d" %(user))
               print("COMPUTER: %d" %(comp))
#--------------------------------------------------------------------------------



print(stone_paper_scissor())

这是我期望的输出：

Choose either of the following:
     stone, paper, scissor
ENTER YOUR GUESS:paper
----------------------------------
YOU WIN!
----------------------------------
COMPUTER:stone
USER:paper
USER: 1
COMPUTER: 0
ENTER YOUR GUESS:scissor
----------------------------------
YOU WIN!
----------------------------------
COMPUTER:paper
USER:scissor
USER:  2
COMPUTER: 0
ENTER YOUR GUESS:paper
----------------------------------
YOU LOSE!
----------------------------------
COMPUTER:scissor
USER:paper
USER: 2
COMPUTER: 1
None

Process finished with exit code 0

但是我得到的输出是不期望的：

Choose either of the following:
     stone, paper, scissor
ENTER YOUR GUESS:paper
----------------------------------
YOU WIN!
----------------------------------
COMPUTER:stone
USER:paper
USER: 1
COMPUTER: 0
ENTER YOUR GUESS:scissor
----------------------------------
YOU WIN!
----------------------------------
COMPUTER:paper
USER:scissor
USER:  1
COMPUTER: 0
ENTER YOUR GUESS:paper
----------------------------------
YOU LOSE!
----------------------------------
COMPUTER:scissor
USER:paper
USER: 0
COMPUTER: 1
None

Process finished with exit code 0

我知道错误背后的原因（我正在def()下使整个程序循环。结果，我得到了意外的结果）。我实际上是想从社区获得解决方案来解决我的问题。每一个建议都会受到赞赏。

谢谢

Answer 1

您必须在for循环上方使用comp = 0和user = 0，以便它们不会在每次迭代中重置。更好的做法是使用类，以便您可以更好地管理游戏

  comp = 0 # computer's score
  user = 0 # user's score
  for i in range(3):
    guess = ("stone", "paper", "scissor")# guess
    user_g = input('ENTER YOUR GUESS:')
    user_g.lower()
    comp_g = choice(guess) #computer"s guess

Answer 2

主要问题是在循环的每次迭代中将comp和user重置为0。将这些行移到for循环的开始上方。其他几点：

您重复赢/输码六次；您可以使用其他功能，也可以将其公用部分移到不同的if/else块之后
或者您也可以根据列表中元素的顺序来确定赢/输的猜测！
您应该检查用户输入是否有效
如果是“绘制”，则应使用continue而不是break
您可以在函数中添加一个参数，以进行轮数
该函数不会return执行任何操作，因此无需print结果

这是我的版本：

def stone_paper_scissor(rounds):
    guess = ("stone", "paper", "scissors")
    comp = 0
    user = 0
    print("Choose either of the following:")
    print(*guess)
    for i in range(rounds):
        user_g = input('ENTER YOUR GUESS: ').lower()
        if user_g not in guess:
            print("invalid choice")
            continue
        comp_g = choice(guess)
        if comp_g == user_g:
            print( "IT'S A DRAW!" )
        elif guess[guess.index(user_g) - 1] == comp_g:
           print( "YOU WIN!" )
           user += 1
        else:
           print( "YOU LOSE!" )
           comp += 1
        print("COMPUTER " + comp_g)
        print("USER "+ user_g)
        print("USER: %d" %(user))
        print("COMPUTER: %d" %(comp))

如何进行循环，以使该点每次转动都累加到“用户”或“比较”中？
