[Biopython] IPI fetching

[Yvan Strahm]

Hello All,

I have a project with a bunch of IPI access number and need to get their fasta sequence. Now I am 
using the SRS web site to get these sequence.
I found a old thread on Biopython-dev about IPI parseing 
(http://portal.open-bio.org/pipermail/biopython-dev/2001-December/000771.html), so I tried to use 
ExPASy.get_sprot_raw to get the sequence with no luck.

Does anyone know how I can use the IPI accession number directly in Biopython?

Thanks for your help,
cheers,
yvan
