Python Assertions — Summary
Despite these caveats I believe that Python’s assertions are a powerful
debugging tool that’s frequently underused by Python developers.
Understanding how assertions work and when to apply them can help
you write Python programs that are more maintainable and easier to
debug.
It’s a great skill to learn that will help bring your Python knowledge to
the next level and make you a more well-rounded Pythonista. I know
it has saved me hours upon hours of debugging.
Key Takeaways
• Python’s assert statement is a debugging aid that tests a condi
tion as an internal self-check in your program.
• Asserts should only be used to help developers identify bugs.
They’re not a mechanism for handling run-time errors.
• Asserts can be globally disabled with an interpreter setting.
