从另一个文件将编码导入新的 tkinter

Question

我有一个名为 wckcalendar.py 的文件。我想将此日历导入另一个具有按钮的 tkinter qw.py。我想在同一个 tkinter 上显示来自 wckcalendar 文件的按钮和日历。

但我得到错误：

  File "C:/Python27/qw.py", line 1, in <module>
    import wckCalendar
  File "C:/Python27\wckCalendar.py", line 115, in <module>
    root.mainloop()
NameError: name 'root' is not defined
>>> 

问题：我没有在同一个窗口中显示我的按钮和日历。请帮助！ qw.py

您的最后一条语句 root.mainloop() 没有正确缩进，将在模块导入的上下文中运行，这不是您想要的

我在您的代码中看到了一些其他问题，例如函数保存对象的局部变量：它们将在函数返回后被垃圾回收
