For what bioinformatics tasks is Biopython more adapted than Bioperl?

This usually comes down to religious issues, so let me try and steer it back to more objective grounds:

• What language do you know (better)? Use the library for that one.
• If you know neither and will be learning a language to use the library, the majority opinion would be that Python is easier to learn.
• However, some people say that they "click" with Perl better
• Python is what the majority of bioinformaticians are using at the moment (about 60%). And there is a virtue and aid in using what everyone else is.
• What are your colleagues / collaborators going to be using?
• Broadly, newer libraries tend to be written in Python.
• Conversely, many sing the praises of regular expressions and string handling in Perl, citing speed and ease of use.
• I think the numerics support in Python may be markedly better than that in Perl.
