Python: Request handler in Flask

I'm learning Flask, and the request handling seems to be like:

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

So I end up defining the functions for all my routes in a single file. I'd much rather have functions for a model in its own file, e.g. get_user, create_user in user.py. I've used Express (node.js) in the past, and I can do:

user = require('./models/user')
app.get('/user', user.list)

where user.coffee (or .js) has a list function.

How do I do the same in Flask?

From the docs:

A decorator that is used to register a view function for a given URL rule. This does the same thing as add_url_rule() but is intended for decorator usage

The add_url_rule docs elaborate:

@app.route('/')
def index():
    pass

Is equivalent to the following:

def index():
    pass
app.add_url_rule('/', 'index', index)

You can just as easily import your view functions into a urls.py file and call add_url_rule once for each view function there instead of defining the rules along side the functions or use the lazy loading pattern.
