为什么不工作，我在User and Pass中输入用户名和密码，将其添加到列表中，但登录时不会调用列表，只是说它是错误的。

Answer 1

User1和Pass1是字符串;正如他们的名字所示，UserList和PassList列出了。没有字符串可以等于列表。

Answer 2

那是因为您将类型数组的UserList与String进行比较，因此它将在那里返回false：

 if User1 == (UserList) and Pass1 == (PassList)

Answer 3

if User1 == (UserList) and Pass1 == (PassList):

您尚未在列表中搜索信息

if User1 in UserList:     #is User1 in the list? 
   if Pass1 == PassList[UserList.index(User1)]:
      print ("Log in Success")
