我目前正在尝试创建一个基本的 Gmail 客户端，并且我正在尝试在两个类之间共享我的登录详细信息，Authen并且Application. 我需要访问在Authen课堂上输入的学分，但我不知道该怎么做。这是我当前的代码，在课堂上Application：

Username_mine = passcheck.Create_Widgets.Username.get()
Password_mine = passcheck.Create_Widgets.Password.get()
contents = self.Body.get("0.0", END)
FROM = "Unknown"
subject = self.Subject_Entry.get()
recipients = self.To_Entry.get()
server = smtplib.SMTP('smtp.gmail.com:587')
server.ehlo()
server.starttls()
server.login(Username_mine, Password_mine)
server.sendmail(FROM, recipients, contents)

当我运行代码时，我收到错误：

Exception in Tkinter callback
Traceback (most recent call last):
  File "/Library/Frameworks/Python.framework/Versions/2.7/lib/python2.7/lib-tk/Tkinter.py", line 1410, in __call__
    return self.func(*args)
  File "/Users/BigKids/Desktop/Coding/Python 2/Email/Email Send GUI V1.py", line 112, in send_cmd
    Username_mine = passcheck.Create_Widgets.Username.get()
AttributeError: 'function' object has no attribute 'Username'

预先感谢您的帮助。

编辑这是我的代码：

您收到错误是因为它Create_Widgets()是类的方法函数Authen，所以self.Username = Entry(self)它是Username实例的属性，而不是方法。鉴于此，假设passcheck是这样一个实例，我认为您需要编写：

Username_mine = passcheck.Username.get()

Create_Widgets 是一个函数而不是一个类，因此您无法访问其中的 .Username 。

您需要做的是将 Authen 的实例传递给 Application 类，并将其存储在 self.authen 中。然后Application中的函数可以做：self.authen.Username

通过简要浏览您的代码，也许您可​​以修改您的__init__for Application，使其接受“authen”变量：

def __init__(self, authen):
  # Other stuff.
  self.authen=authen

然后你会初始化应用程序 app = Application(authen=self)

在 中send_cmd()，您会调用：Username_mine = self.authen.Username.get()

您确定 Username 是函数对象的实际成员吗？（确保您在函数类中使用self.Username而不是Username ）
