Starting With Python's assert Statement

The rest of the course covers how to:
– How assert can help you document, debug, and test your code
– How assertions can be disabled to improve performance in production
– What common pitfalls you might face when using assert statements
– Working with the PYTHONOPTIMIZE environment variable
