The square ones designate lists:
http://docs.python.org/tut/node7.html
The rounded ones designate tuples:

The short of it is that lists can change and tuples can not.
<commentary>The long of it is that there are deep computer-science
issues that distinguish the two and the differences become more
important the more you know (presumably). However, I have been
programming this language for 5 years, and I still can't figure out the
necessity for having both. I have heard all of the arguments, however
but none are terribly pursuasive.</commentary>
Practically speaking, however, if you don't know which one to use, then
use the square kind.
