Sample code from my "Introduction to Flask" presentation. The slides for this presentation are available at https://speakerdeck.com/miguelgrinberg/introduction-to-flask.

• Flask (pip install flask) is required for all the examples.
• Flask-Bootstrap (pip install flask-bootstrap) is required for examples 4 and up.
• Flask-WTF (pip install flask-wtf) is required for examples 5 and up.

You can create a virtual environment and install the required packages with the following commands:

$ virtualenv venv
$ . venv/bin/activate
(venv) $ pip install -r requirements.txt

With the virtual environment activated you can cd into any of the examples and run the main script.

For examples 1-6:

(venv) $ python hello.py

For example 7:

(venv) $ python manage.py
