Awesome Python Features Explained Using the World of Magic

As outlined in my blog post, I decided to take on a new habit using a technique I found on the 'get disciplined' subreddit.

As one of my new habits I chose: "Code for 15 minutes every day". As part of the habit I've started creating a series of blog posts on important and awesome Python features, including object oriented programming, properties, function annotations, duck typing, etc.

Since I was bored by the usual tutorial examples, I looked for a topic that would make it fun to study and implement the concepts. And since I absolutely love Harry Potter, I started creating my own magical universe around the topics. A short introduction into my magical universe - The Tales of Castle Kilmere can be found here. So if you like magic and want to improve your Python knowledge and skills, get right into it!

A logbook of what I worked on each day can be found on my website.

The code runs in Python 3.6, the code on data classes requires Python 3.7 (or you pip install data classes for Python 3.6).

Start date: 07/23/2018

In case you can't access my website, the blog posts can also be found in this repository (see folder 'blog_posts').

Running pytest

In case you get ImportError: no module named magical_universe when running pytest from within the test_code directory, take a look at this post and try running pytest from the root directory (which is the home directory in my case) using python -m pytest magical_universe/test_code/.
