尽管条件满足，循环仍然没有结束

Question

我已经构建了一个代码来执行一个简单的任务：接收用户名和密码，检查它们是否满足条件，如果不正确则重复该过程，如果正确则停止程序。但是while循环不会停止，程序会继续运行。我在下面插入了代码。当条件满足时，如何使while循环停止？你知道吗

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)

您需要为变量confirmation指定函数loginConfirmation的返回值，以便中断while循环。你知道吗

在给定的代码中，变量confirmation的值总是0，因此while循环的中断条件永远不会满足。你知道吗

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)
