Learning Python & Flask

This is my adventure of learning Python and Flask.

Follow Along

I'm following the multi-part tutorial at https://blog.miguelgrinberg.com/post/the-flask-mega-tutorial-part-i-hello-world for this repo.

Web Application

The tutorial walks you through developing a microblogging server that he calls microblog.

Here's some of the components he walks us through:

• User Management
• Database Management
• Web Forms
• Pagination of long lists
• Full text search
• Email notifications/alerts
• HTML Templates
  • I will be using Editorial from HTML5 UP
• Support for multiple languages
• Caching and performance optimizations
• Debugging techniques for dev/prod
  • I'm super excited about this one!
• Installation of all on prod server
  • I believe we end up using Heroku at the end of the tutorial

Requirements

I tried this on Python 2.7, but found that Python 3 just worked. Pylint with cray-cray until I switched over the Py3... so just use it from the get-go and you'll be good.

Other than that, I used PowerShell in VS Code and went to town there for my terminal through out the tutorial.

Install Python 3

Go here: Download Python 3.x

Install Flask

Create your microblog directory and then create a virtual environment for Python 3 for development by doing

$ python -m venv flask

That will create a virtual environment for Python 3 in a directory named Flask.

Flask Dependencies for Microblog

We'll use pip that was installed into our Python 3 virtual environment to download & install all necessary dependencies.
