You're like me. And yes I haven't found a single strong reason to move to python. Technically, is there anything good about Python as compared to PHP, other than being a 'cooler' language ?
A lot of programmers really enjoy that additional structure and I have to admit that when it comes to reading someone else's source, Python typically makes for a more enjoyable experience than Perl.
At the end of the day it's up to you to decide if Python has any value for you, and the only way you're going to find that out is to take it for a test drive.
