Interestingly enough, one of the reasons I'm learning Python is because I don't know Perl, which is used at my workplace. My experience is that Python works well as a 'glue' language for doing systems things.

EDIT: I should mention, I'm not just refusing to learn Perl, I'm just choosing to use Python where Perl would have been used before. No other Devs on our team are Perl experts, all our Perl code is Legacy.
