I know it is valid, according to the Tkinter source, every widget constructor has a 'master=None' default. What happens on doing this?
Tkinter creates a default Tk object and uses that as the master. >>> t = tkinter.Text() >>> t.master <tkinter.Tk object .>
In what circumstance, we do it this way? and will it cause any trouble?
I believe it is OK if you always do it that way within a single application. But I prefer to have an explicit reference and use that for .after calls and some others.
