In general, what follows is a collection of potentially tricky behavior that might seem strange at firs

Testing Your Code¶ Testing your code is very important. Getting used to writing testing code and running this code in parallel is now considered a good habit. Used wisely, this method helps to define your code’s intent more precisely and have a more decoupled architecture. Some general rules of testing: A testing unit should focus on one tiny bit of functionality and prove it correct. Each test un

Pipenv & Virtual Environments¶ This tutorial walks you through installing and using Python packages.
