I really like Python, and use it on a daily basis but I found that after enough experience in Clojure, I prefer it when I have the choice and there isn't a compelling reason to use Python instead.
This isn't a criticism by the way, I do understand that people have different preferences of language idioms, and I do occasionally find myself scratching my head about the idiomatic Clojure way to solve a problem that wouldn't have been so hard for me in Python.
While I don't think Python is a bad language at all, it has some limitation that I am becoming more and more being aware of them - lack of static typing, limitation of lambdas, speed is an issue sometimes, but on the other hand it's very easy for me to be productive in it.
I am pretty sure that its lack of features is making Python easier to "master" (I don't claim to master it, just that I am more productive with it), but this lack can be limiting sometimes, so I am trying to find a solution to have both power and proficiency.
