Player 1切换到Player 2，如何从Player 2切换回Player 1？这是一个双人猜数游戏。

Question

我正在写一个2人猜数游戏的Python代码。玩家1尝试猜测，如果他们猜错了，程序应该转到玩家2。如果玩家2猜错了，程序应该返回到玩家1。我使用的是我在堆栈溢出中找到的“主动、被动”代码，它在从玩家1转到玩家2时起作用，但如果玩家2猜错了，我就不能回到玩家1。

如果他们真的做对了，代码也不会说出编程的句子。它只是移动到Player 2，或者什么都不打印。

import random
answer= random.randint(1,100)
print('The bingo answer is', answer, '.', 'This will not be shown to the user.')

upperLimit=100
lowerLimit=1
guessingPlayer= ""

active, passive = "1", "2"
while guessingPlayer== "1":
    print('~ ', lowerLimit, 'to ',upperLimit, '~')
    guess = input('Player 1:')
    if int(guess) == answer:
      print("Bingo! Player 1 wins!")
      break
  
else:
    guess= input('Player 1:')
    if int(guess) < answer:
      print('Wrong!')
      lowerLimit=guess
      print('~', lowerLimit, 'to', upperLimit, '~')
    if int(guess)>answer:
      print('Wrong!')
      upperLimit=guess
      print('~', lowerLimit, 'to', upperLimit, '~')
      passive, active= "1", "2"

while guessingPlayer== "2":
  guess = input('Player 2:')
  if int(guess) ==answer:
    print("Bingo! Player 2 wins!")
    break

else:
  guess= input('Player 2:')
  if int(guess)<answer:
    print('Wrong!')
    lowerLimit=guess
    print('~', lowerLimit, 'to', upperLimit, '~')
  if int(guess)>answer:
    print('Wrong!')
    upperLimit=guess
    print('~', lowerLimit, 'to', upperLimit, '~')
    active, passive= "1", "2"

你可以使用一个函数，这将大大简化你的代码。

值得一提的是，在Python中，变量命名约定不是驼峰式大小写(myVariable)，而是使用下划线(my_variable)。

import random

answer = random.randint(1, 100)
print('The bingo answer is', answer, '.', 'This will not be shown to the user.')


def ask_player(player_number, lower_bound_, upper_bound_):
    """ asks the player, returns True if the guess is correct, False o.w. """
    print('~ ', lower_bound_, 'to ', upper_bound_, '~')
    current_guess = input('Player %s:' % player_number)
    if int(current_guess) == answer:
        print("Bingo! Player %s wins!" % player_number)
        return True
    return False


if __name__ == "__main__":
    upper_limit = 100
    lower_limit = 1
    guessing_player = ""

    active, passive = "2", "1"
    playing = True
    while playing:
        active, passive = passive, active  # switch roles
        playing = not ask_player(active, lower_limit, upper_limit)
