I have and do use both perl and Python on a fairly regular basis.
Both languages have their places. But, as much as I love perl, I tend to relegate it to tasks revolving around text manipulation due to it's built in Regular Expressions operators. Python seems to just work better for larger projects, and is (usually) easier to understand. Perl has a tendency to encourage efficiency at the cost of readability.
That said, you asked, which should you learn, not, which should I use. That may be a very different answer, depending upon your reasons. If you love just learning things to see how they work and you have a habit of constantly refactoring for simplicity, learn perl. If you want to learn a language to make yourself more marketable, Python is probably a better choice (although you may want to look into something completely different depending upon your intended field).
