Python is a very popular open-source programming language. PostgreSQL is a very popular open-source relational database. It shouldn’t surprise us, then, to discover that many people are using PostgreSQL to store and retrieve data in their Python projects. This talk, given by Christophe Pettus, introduces PostgreSQL from the perspective of a Python programmer; the emphasis is on PostgreSQL, but there are also Python elements here.  If you are thinking of using PostgreSQL in your project, but feel like you don’t know enough about it, this is a good place to start.
