In this chapter, we've shown you the Python DB-API (version 2.0). There are at least three implementations of the PostgreSQL/DB-API interface; we've used the PyGreSQL implementation because that it is the one you are most likely to have (it's distributed with PostgreSQL).
As we mentioned at the start of this chapter, you can also use the PyGreSQL interface without using the DB-API wrapper. PyGreSQL is a nifty toolkit, but the DB class offers some nice features.
You've made it through all the chapters devoted to PostgreSQL programming. In the next section, we'll be examining the administrative tasks involved in creating and maintaining a PostgreSQL environment.
