I learned programming in Perl 2 yrs ago when I started supporting an in-house-developed Java/Unix based application. I have seen Python gaining ground since then and got interested in it.
Today, I came across a bunch of very interesting and absorbing articles about several programming languages but mostly focused on lisp, perl and python.
It all started with Paul Graham's "Revenge of the Nerds" article. He is a Lisp expert and to be honest I did not know much about lisp until I read his article. It was a provocative one and he got a lot of responses which he responded with "Re: Revenge of the Nerds".
After you read these two, you would probably want to keep on reading how Python Lovers responded:
Paul Prescod has written a rebuttal to Revenge of the Nerds, On the Relationship between Python and Lisp. Peter Norvig (Google's Director of Research) has also written about this topic in Python for Lisp Programmers.
