Answer: An assertion is a boolean expression that checks if assumptions made in the code remain true while development
Assertions are boolean expressions that enable you to test the assumptions you have made in your code. They are used in unit tests to check if certain assumptions remain true while you're developing your code. For example, `assert func() == expected_value`.
