The PyDB2 package provides a Python DB API 2.0 interface to IBM's DB2 database management system. The package also includes various tools for working with DB2.
pydb2 is fast and stable
Good, lacks some documentation, but use test_basic.py as guide. Also if you cannot find sqlcli1.h while building, you must install the development libs that come with DB2. This can be done by doing a custom install
Can not use it because of two big documentation omissions. First, no info about building requirements. This needs IBM's libraries and include files. I finally got by this after a few hours (get them by installing IBM DB2 Express-C). Second, no code examples. In particular: How do you connect to the database? The connect() function does not accept a host parameter.
