When I need such information (most recently with jQuery and Prototype), I usually google: jQuery Prototype OR comparison OR compare OR matrix (the latter term to get a "feature matrix").

(Replace "jQuery" and "Prototype" as needed in the above example.)

You've not specified what that query is and whether other technicalities are involved in addition to the syntactic representation and what the comparison contexts that would be addressed are, are you new to Perl and Python or only to BioPerl and BioPython, what do you look for from that comparison? what Perl-specific characteristics you'd wanna check?, you see, There can be a lot of information if you show the right focus...

Here are some starters however,

• BioPython ClustalW
• BioPerl ClustalW

I wish you best of luck, I am not being rude as much as I am being only motivational Pubudu and I advice to stick to learning one thing at a time...

So you want us to do your (home)work for you?

I searched everywhere in the net

I doubt it.

• Try Google with "bioperl" and then with "biopython" as your search items
• Proceed from there.
