Question

我已经构造了一个代码，以执行一个简单的任务，即输入用户名和密码，检查它们是否符合条件，如果不正确则重复该过程，或者如果正确则停止该程序。但是，while循环不会停止，程序将继续运行。我在下面插入了代码。满足条件后，如何使while循环停止？

def loginConfirmation(user1,user2,pass1,pass2,confirm1,confirm2): 
  if len(user1) > 6:                           
      confirm1 = confirm1 + 1
  else:
      print("Invalid username Player 1")
  if len(user2) > 6:
      confirm2 = confirm2 + 1
  else:
      print("Invalid username Player 2")
  if pass1 == ("password"):                     
      confirm1 = confirm1 + 1
    else:
      print("invalid passsword Player 1")
  if pass2 == ("password"):
      confirm2 = confirm2 + 1
  else:
      print("Invalid passsword Player 2")
  confirmation = confirm1 + confirm2
  return confirmation

confirmation = 0
confirm1 = 0
confirm2 = 0

while confirmation != 4:
     print("Please enter your details below. Usernames must be at least six letters long.")
     user1 = input("Player 1, enter your username: ")
     pass1 = input("Player 1, enter your password: ")
     user2 = input("Player 2, enter your username: ")
     pass2 = input("Player 2, enter your password: ")
     loginConfirmation (user1,user2,pass1,pass2,confirm1,confirm2)

您需要将函数confirmation的返回值分配给变量loginConfirmation，以打破while循环。

在给定的代码中，变量confirmation的值始终为0，因此，永远不会满足while循环的中断条件。

使用以下内容更新代码：

def loginConfirmation(user1,user2,pass1,pass2,confirm1,confirm2): 
  if len(user1) > 6:                           
      confirm1 = confirm1 + 1
  else:
      print("Invalid username Player 1")
  if len(user2) > 6:
      confirm2 = confirm2 + 1
  else:
      print("Invalid username Player 2")
  if pass1 == ("password"):                     
      confirm1 = confirm1 + 1
    else:
      print("invalid passsword Player 1")
  if pass2 == ("password"):
      confirm2 = confirm2 + 1
  else:
      print("Invalid passsword Player 2")
  confirmation = confirm1 + confirm2
  return confirmation

confirmation = 0
confirm1 = 0
confirm2 = 0

while confirmation != 4:
     print("Please enter your details below. Usernames must be at least six letters long.")
     user1 = input("Player 1, enter your username: ")
     pass1 = input("Player 1, enter your password: ")
     user2 = input("Player 2, enter your username: ")
     pass2 = input("Player 2, enter your password: ")
     confirmation = loginConfirmation (user1,user2,pass1,pass2,confirm1,confirm2)

Answer 2

您只需要重新排列一下代码，请尝试以下代码：

<span class="article-price">
    <span>
        <span>149,99</span>
        <span>€</span>
    </span>
</span>
<div>your installment is <span id="installment"></span></div>

NB：

1-每次通话后，两个变量Confirm1和Confirm2必须重置为零

2-您必须将函数'loginConfirmation'的输出值分配给确认变量

尽管满足条件，但循环未结束
