【问题描述】:
解决了: 正如@furas 所说,我在销毁窗口后尝试访问 email_text,因此 email_text 不再存在。
我正在尝试通过使用 tkinter 从条目中获取电子邮件和密码来自动登录网站。该代码获取电子邮件和密码并将其输入站点,并成功登录。但是我收到有关 email_text.get() 行的错误。
本来我有一个prepare()和error()函数,所以如果登录不成功,它会调用error()并提示他们重新登录。当时我遇到了同样的错误,想知道这是否是函数中小部件之间存在冲突的问题?所以我只是试图将它简化为一个,但我仍然遇到同样的错误。我有此代码的 3 个不同版本,并且一直在移动一些位,所以我可能没有从其他 2 个版本中移动需要的东西,但我无法弄清楚我可能缺少哪个部分。

如果登录成功,网页应该关闭,但它保持打开状态,我收到此错误:

您的问题可能是
while True在get_email_pass()内运行多次email_text.get()- 但在运行email_text.get()第一次运行my_window.destroy()之后,email_text在 @ 时不存在987654329@ 第二次运行email_text.get()。这会给出错误“无效的命令名称”
