新行在Python中是如何表示的？

Question

我有一份特殊人物名单：

specialCharList=['`','~','!','@','#','$','%','^',
                         '&','*','(',')','-','_','+','=',
                         '|','','{','}','[',']',';',':',
                         '"',',','.','<','>','/','?',"'",'\\',' ']

我需要包括一些字符表示法，当用户按下enter按钮输入新行时。我试过'\n'，但没用。有什么想法吗？在

下面是更多信息

对不起，我应该指定的。我在做一个基本的加密/解密应用程序。它的作用是将字符移到右边6个位置，然后输出。在

例如，abc将作为ghi输出 e、 输出为123克789

我也用特殊字符做了同样的事情。使用下面的列表查看它是如何工作的。在

specialCharList=['`','~','!','@','#','$','%','^',
                         '&','*','(',')','-','_','+','=',
                         '|','','{','}','[',']',';',':',
                         '"',',','.','<','>','/','?',"'",'\\',' ']

例如~！将输出为^&

当有人在文本框中输入文本、数字和特殊字符的组合并进行加密时，一切正常，但如果有人输入了一行新行（例如，按回车键），我会得到一个错误。在

index=specialCharList.index(tbInput[i])

值错误：u'\n'不在列表中

大多数文本框（主要是Windows）需要\r\n切换到下一行。\n单独使用是不够的。在
