In this chapter we have discussed different strategies for hardening your code. In particular, you have learned how to install third-party pip packages securely, how to privatize variables in Python, how to keep a directory of tests/ organized, and the dangers of wildcard imports. You can use these lessons to improve your code base’s organization and help avoid dangerous classes of unexpected bugs.
No island will ever be built rigorously enough to contain all its dinosaurs, but you can always improve your system just a little bit more to make it resilient to life’s efforts to free itself.
You’ve reached the end of this book, but only the beginning of your possible experience with Python. You’ve covered a lot of ground already. In the beginning of this book, you explored Python’s interpreted nature and learned techniques for improving your code with static analysis tools like flake8. You moved on to touring some of the finer parts of the standard library including the collections module and tempfile. As the book progressed, you built meta-level understanding of Python projects including how to harness concurrent code and the inherent dangers of pickle and pip.
I’ve been writing Python for my entire adult life, and I still find myself learning new patterns, discovering new tools, yelling in frustration at some inane bug, and experiencing an intoxicating high after fixing that bug. I hope you can experience the same.
