How to divide flask app into multiple py files?

My flask application currently consists of a single test.py file with multiple routes and the main() route defined. Is there some way I could create a test2.py file that contains routes that were not handled in test.py?

@app.route('/somepath')
def somehandler():
    # Handler code here

I am concerned that there are too many routes in test.py and would like to make it such that I can run python test.py, which will also pick up the routes on test.py as if it were part of the same file. What changes to I have to make in test.py and/or include in test2.py to get this to work?

You can use simple trick which is import flask app variable from main inside another file, like:

test_routes.py

from __main__ import app

@app.route('/test', methods=['GET'])
def test():
    return 'it works!'

and in your main files, where you declared flask app, import test-routes, like:

app.py

from flask import Flask, request, abort

app = Flask(__name__)

# import declared routes
import test_routes

It works from my side.

This task can be accomplished without blueprints and tricky imports using Centralized URL Map

app.py

import views
from flask import Flask

app = Flask(__name__)

app.add_url_rule('/', view_func=views.index)
app.add_url_rule('/other', view_func=views.other)

if __name__ == '__main__':
    app.run(debug=True, use_reloader=True)

views.py

from flask import render_template

def index():
    return render_template('index.html')

def other():
    return render_template('other.html')

If you need split blueprint to separate files you can use snippet:

# app.py

from blueprint_module import blueprint

app = Flask(__name__)
app.register_blueprint(blueprint)

# blueprint_module\__init__.py

from flask import Blueprint

blueprint = Blueprint('my_blueprint', __name__)

from . import page

# blueprint_module\page.py

from . import blueprint

@blueprint.route("/url", methods=['GET'])
def hello():
  return 'hello world'
