Python 从tkinter中的文件1按下按钮时如何跳转运行/执行文件2

我有2python文件file1和file2，它们是用tkinter编码的

文件1是

欢迎页面

有一个按钮以医生身份登录

文件2是医生将在其中输入其凭证的

登录页面。
两个文件都用tkinter编码

运行：-

欢迎文件（文件1）将以GUI形式运行
按下文件1上的按钮时，应将其重定向到
登录页面（文件2）
注:-

两个文件都不同

文件1 Welcome.py

文件2 login.py

按下欢迎页面的按钮登录页面应以gui形式执行

请帮助我有一个大学小项目，但我被困在这里了……

这绝对不是从主窗口打开第二个窗口的正确方法。在Tkinter中，如果您需要添加窗口，我们将使用
Toplevel（）
而不是使用另一个
Tk（）
，尽管它可以工作，但不是推荐的方法

这里不需要
importlib
，无需使用它即可轻松完成

就像您可以在file.py中定义函数一样，
在主文件中导入文件
，然后按文件1中的按钮通过
文件调用它。运行\u登录

示例：

def doc():
    A = Application(master = root)

文件2

def Run_Login():
    # creating the object
    root = Toplevel()

    # resolution of the window
    root.geometry("1520x790+0+0")
    root.title ("ABC HOSPITAL")
    # root.iconbitmap('hospital.ico')

    # preventing the resize feature
    root.resizable(False, False)
    Application(root)

文件2：

import file

def doc():
    file.Run_Login(master=root)


此外，在应用程序类中继承Toplevel将使您的工作更加轻松，因为这样您就可以从文件导入应用程序中导入文件1
中的类了。然后在doc中你可以调用它

示例：

def doc():
    A = Application(master = root)

我希望这能解决你的问题。
嗨，朴智星！在login.py中检查您的按钮命令，似乎您想要调用按钮本身，这没有任何意义。您可能在文件2中的应用程序类中缺少了
login（）
函数。实际上，这是一种未命中类型。我尝试了很多方法，因此它错误地保留了下来。我将其删除了。对不起。。。。。。。。。。。。。你知道我如何解决上述问题吗？非常感谢Saad
