Comparing perl and python

[Mridul]

 Here's something to chew on as far as speed is concerned:

 Python2C
    More recently, Bill Tutt and Greg Stein developed Python2C. This
    translates Python to C code. Mostly, the C code ends up manipulating
    PyObjects in much the same way as if you had recreated the Python code
    in C using the high level Python / C API. That is, you'll get a speed
    up from the fact that there's no byte-code interpreter loop, but
    that's less than most people expect. (There's been a lot of talk about
    global program analysis and type deduction. When these ideas bear
    fruit, more dramatic speed ups will become possible.)


 By the way has anybody used it?????????If so please give us a feedback and
 from where to download it from........
