First of all - I like Python.
Second - we have some prototype for mysql-server configuration written in Python I never tried before.
So I check-in code from subversion and try to run. Unfortunately it exits with some errors like "couldn't initialize UI". So I open the code in Eric - great Python debugger.
With breakpoints, globals and locals variables dispatcher it was really easy to find problematic places in code. Also possibility to write code interactively into interpreter is very helpful.
And finally module runs ;-)
Sorry, video is pretty slow - probably ati driver problem ;-(
