I’m one of the many Biopython participants, having first started using the code back in 2004 or there abouts.
My personal Biopython git branches can be found on github.
My main contributions are the Bio.SeqIO and Bio.AlignIO modules and some of the underlying parsers. I’ve also worked on Biopython’s BioSQL interface, and the tutorial and other Documentation.
There are some nice examples on my python pages.
