Gravatars in Python 2.5

Cory Wright wrote in with his method for generating Gravatar URLs in python (seems to require 2.5 or better.) It’s truly great when we get submissions like this. Not only do we get to see how people are using Gravatar, but we get to share that information to help other people who might be thinking about using Gravatar themselves!

# import code for encoding urls and generating md5 hashes
import urllib, hashlib

# Set your variables here  
email = "Someone@somewhere.com"
default = "http://www.somewhere.com/homsar.jpg"
size = 40

# construct the url 
gravatar_url = "http://www.gravatar.com/avatar.php?" 
gravatar_url += urllib.urlencode({'gravatar_id':hashlib.md5(email.lower()).hexdigest(), 'default':default, 'size':str(size)})
