A list of many thousands of Python Packages is found in the pypi index. Try the "browse Packages" link to see packages organized by topic. Some of these packages are not easy for beginners to use, some of them have not been updated for newer Python versions and distributions; use some caution and search for additional documentation (perhaps user reviews as well) before trying them.

The chapter does not mention what is another, increasingly popular way to install packages: the virtualenv method of installation. The concepts behind Virtual Environments is an advanced topic, explained in PEP 0405.
