Flask

because sometimes a pocket knife is not enough

Flask is a microframework for Python based on Werkzeug, Jinja 2 and good intentions. And before you ask: It's BSD licensed!

Flask is Fun

from flask import Flask
app = Flask(__name__)

@app.route("/")
def hello():
    return "Hello World!"

if __name__ == "__main__":
    app.run()

And Easy to Setup

$ easy_install Flask
$ python hello.py
 * Running on http://localhost:5000/
