The view function did not return a valid response. The return type must be a string, tuple, Response instance, or WSGI callable, but it was a bool.

Now, it returns the more readable

Flask
=====
Flask is a lightweight `WSGI`_ web application framework. It is designed
to make getting started quick and easy, with the ability to scale up to
complex applications. It began as a simple wrapper around `Werkzeug`_
and `Jinja`_ and has become one of the most popular Python web
application frameworks.
Flask offers suggestions, but doesn't enforce any dependencies or
project layout. It is up to the developer to choose the tools and
libraries they want to use. There are many extensions provided by the
community that make adding new functionality easy.
Installing
----------
Install and update using `pip`_:
.. code-block:: text
pip install -U Flask
A Simple Example
----------------
.. code-block:: python
from flask import Flask
app = Flask(__name__)
@app.route('/')
def hello():
return 'Hello, World!'
.. code-block:: text
$ env FLASK_APP=hello.py flask run
* Serving Flask app "hello"
* Running on http://127.0.0.1:5000/ (Press CTRL+C to quit)
