Python 在 .txt 文件中以不同方式保存密码 [关闭]

Question

我在 PyCharm 中创建了一个基本的 python 登录系统。所有功能都有效。所有用户名和密码都保存到一个 .txt 文件中。当我创建新的用户名和密码时，PyCharm 和 .txt 文件中的密码不同。例如，我在 PyCharm 中创建了用户名 robotman，密码 7777Spy007。在 .txt 文件中，用户名为 robotman，密码为 874775653b3c315b236d8b9fd21a1a330eb613c78c7b80ddb7c96f36a7b35452。请参考.

我可以在 PyCharm 中使用用户名 robotman 和密码 7777Spy007 登录。请参阅.

然而，当我在 PyCharm 中“查看帐户”时，它反映了 .txt 文件。请参阅.

我需要在 PyCharm 中“查看帐户”来显示“robotman 7777Spy007”我应该怎么做才能解决这个问题？
