columnconfigure / rowconfigure in "A First Real Example" - Python

[Hisato Shima]

Thank you for your excellent tutorial. It is really helpful.

In your first real example code, the size of mainframe does not follow the

main window size when it is changed. (I am using Python code)

I think columnconfigure / rowconfigure messages should be sent to the root window object

rather than the mainframe object, like

root.columnconfigure(0, weight=1)

root.rowconfigure(0, weight=1)
