What's Perl good at or better than Python.

Making me money. I make a whole lot more money doing Perl work than I did when I was coding in Python.

A company can hire 50 people out of school, then another 50 who have been in the field a few years to write Python for a dime a dozen. Perl experts are much, much harder to come by, so the jobs typically pay far more. I work for a company doing full time Perl work, and I still have several very well paying clients who use my services several times per year. The hourly rate for those clients is significantly more than I could (and have) made by doing similar work in Python.

With that said, the jobs are much harder to come by. You're all but guaranteed a job if you're worth your salt with Python coding.

Perl is and always been hands down my favourite language, and I never see that changing. I even prototype most of my code in Perl for most of the other languages I write in (C/C++, C#, Python etc), even my microcontroller code before I write it.
