[Biopython] Code for protein alpha helix prediction

[Frank Kauff]

Hi all,

I've recently been asked to help with screening protein sequences for 
certain features, something I don't really know much about... Yet!

My questions: Is there some code in Biopython that allows for a quick 
check whether an amino acid sequece is likely to be a alpha helix? 
Couldn't find any. Or is there an algorithm that could be 
straightforwardly implemented in python, or a commandline tool that 
could be called from within a python script?

Thanks in advance,
Frank
