md5 shit in python

import os, md5;

for root, dirs, files in os.walk(os.path.abspath('')):
    for f in files:
        e = os.path.splitext(f)[1]
        if (e and e not in [".py",".db"]):
            h = md5.new(file(f,'rb').read()).hexdigest()
            n = h + e
            try:
                os.rename(f,n)
            except WindowsError:
                os.unlink(n)
                os.rename(f,n)
            print n + " " + f

How do I optimize this, I'm watching SICP right now

You have clearly no idea what you're talking about. Not that there is much of a topic to talk about, nop has its purposes, and if you just want to skip a large chunk of code you'd just assemble an unconditional long jump.

FUCK, I SHOULDN'T READ YOUR POSTS. IHBT
