带有ttk日历的Python tkinter

带有ttk日历的Python tkinter,python,tkinter,ttk,Python,Tkinter,Ttk,我正在使用代码在我的Tkinter上创建一个简单的日历。当我把日历放在我的主根窗口上时,日历看起来很好。因此,我决定放置另一个按钮来创建Tkinter toplevel窗口,并在toplevel窗口上再放置一个日历。但这次它未能显示日历,而是给了我一个错误,“TclError:无法将.18913120打包在.18912200.18912400内”。谁能解释一下为什么我会收到这个错误信息 这是我的示例代码: import calendar import sys try: import Tk
