Having completed the TWriting Pythonic Code, Code Linting, and Testing with PyTest module (i.e., Module 8) you should now be comfortable:

• writing a test for an existing function or module

• using test driven development to refactor code

• using tools such as isort and black to automatically reformat code

• using tools such as pylint to identify style issues in code

• correcting the issues identified by a tool such as pylint

1. How a parametrized test can reduce duplication in test code

2. How tools such as black help make code more Pythonic

3. How TDD reduces disposable “main” functions
