Python url encoder script

ok, I have it MOSTLY working, but I need a small fix, it doesn't return the right characters, like < returns %3%63 instead of %3c. My second attempt at a script, maybe it can be helpful to someone for xss once it works. Thanks to anyone that helps! I'm starting to get the hang of it. The other one I made was for trig that calculates the radius of the circle and its sin cos tan sec csc and cot values, if anyone wants it I'll post it later.

edit- holy crap that's a lot of smiles, replace with backwards parenthesis, sorry about that

First: There's a handy little thing called "disable smileys in this post" at the bottom, it helps. ;D

Second: Code is a little messy, and a little silly, seeing that python already has a urlencode() function.

But it works, yes.

0_0 wow I wish I knew that earlier… Ah well, practice at least.
