python microframeworks
A fast, simple and beginner-friendly
overview.
HI, I'm PAUL FINN
Was an enterprise .NET developer for a while
Mostly self-taught in web development
Switched from PHP -> Python, never looked back
I'm now a Web Developer at Saltwater Creative
WHY PYTHON?
High-Level, Beginner Friendly
Extremely Popular
Supportive Ecosystem
Emphasis on testing, documentation
and good coding practices
PYTHON WEB FRAMEWORKS
You've probably heard of
- Admin backend
- User accounts/logins
- Object Relational Mapper (ORM)
- Cache System
- Syndatication System
- Internationaliztion
It's awesome.
You should learn it: djangoproject.com
Some of the best documentation you'll find for an open source project.
WhAT'S A MICROFRAMEWORK?
MICROFRAMEWORKS
For handling HTTP requests
...and responses.
Maybe sessions.
Simple templating.
Not much else.
WHAT ARE WE LOOKING FOR?
Easy to understand
(documentation, minimal magic)
Easy to work with HTTP Request/Response
(GET? POST? Referrer? Cookies?)
URL Patterns/Routing ("REST-ful")
Static assets, deployment, etc.
MOST IMPORTANTLY...
Leaving most of the decisions up to you.
Pick-your-own database engine, templating engine, cookie management, sessions and authentication,
etc.
Very extendable.
START SMALL
Bottle is a fast, simple and lightweight micro web-framework for Python. It is distributed as a single file and has no dependencies.
from bottle import route, run @route('/hello') def hello(): return "Hello World!" run(host='localhost', port=8080, debug=True)
@route('/') @route('/hello/<name>') def greet(name='Stranger'): return template('Hello {{name}}, how are you?', name=name)
from bottle import get, post, request @get('/login') def login_form(): return '''<form method="POST" action="/login"> <input name="name" type="text" /> <input name="password" type="password" /> <input type="submit" /> </form>''' @post('/login') def login_submit(): name = request.forms.get('name') password = request.forms.get('password') if check_login(name, password): return "<p>Your login was correct</p>" else: return "<p>Login failed</p>"

WHAT'S SO GREAT ABOUT FLASK
Well-documented and extremely popular
Better, faster template engine
SQLAlchemy plugin for ORM
More features, better debugger
Flaskr - Tutorial on github
MY PREFERRED STACK
Python & Flask
(with SQLAlchemy, usually)
Deployed on Heroku
Amazon S3 & SimpleDB For Storing Objects/Files
Mailgun (for handling email)
DEPLOYING TO HEROKU
Getting Started With Python on Heroku
(Tutorial with Flask)
FLASK & API's == WIN
Jumping to conclusions...
Python is fun, give it a shot!
Quickly make cool stuff on the web
with Bottle or Flask
Deploy right to Heroku
(or your Apache/nginx server)
Flask can scale!
