With "side" you have only four option: top, right, bottom and left,
with "anchor" you can use some combinations of n, w, s, e or use
center (the default). You can also use anchor and side at same time,
for example x.pack(side='top', anchor=''w'). side='top' is the default
one, it defines where in the master the widget will be packed, anchor
defines the position of the widget in this side you chose.

For using it with pack see the paragraph above.
Now when you use the option "anchor" while creating a Button, it will
be defining where its text and/or image will be placed in the widget,
just like described above. Try creating a Button with some text, pack
it with expand=True and fill='both' and change the value in anchor to
see how it behaves.

Anyway, by now (4 days late) you probably already found out all this :)
