It would be a good idea to modify the examples from this chapter to lay out the widgets in different ways or to tweak the code to function in other ways to get your feet wet.
We recommend that you take a look at the documentation for all three geometry managers in your Python shell using the following commands:
>>> import tkinter
>>> help(tkinter.Pack)
>>> help(tkinter.Grid)
>>> help(tkinter.Place)
You can also find an excellent documentation of Tkinter at http://infohost.nmt.edu/tcc/help/pubs/tkinter/web/index.html.
