Pros:
Freely available.
Python DB-API module available.
Cons:
Difficult to get up and running - some of the procedures just seem arcane (whereas PostgreSQL and MySQL make it easy to create databases and other things).
Python module didn't seem to be readily available for the latest release of SAP DB and didn't work either, even though Jython could connect using JDBC.
Bizarre reliability problems on Windows 2000 - try and start a server and it claims that the server needs restarting, even though the server has just been stopped.
In my opinion, it's better to use PostgreSQL or MySQL, or to evaluate a commercial database system. Your mileage may vary.
