python登 tk页面跳转使用Tkin的Python登录页面，登录页面跳转到index

我为我的ATM模拟程序创建了一个登录页框架，我无法使我的登录按钮正确运行。我的登录页面有两个输入字段，帐号和PIN号码。我希望能够打开一个新的框架窗口，我创建了一个名为“欢迎页面”，如果帐户号码与我创建的帐户号码匹配，如果PIN号码与我创建的PIN号码匹配。如果没有，它将保留在登录页面上。这是我目前为止的全部剧本#!/usr/细心的音响/python

默认帐号1234567和我创建的默认pin是1234。我计划使用pickle模块创建一个包含帐号和pin的字典，但是现在我只想用这些帐号登录。我欢迎任何关于如何实现这一点和如何改进我的脚本的建议，谢谢！在
