The catalog of annotated code examples of all design patterns, written in Python. Because nested code makes it harder to read and understand what is happening. This course will show you how to remove Python anti-patterns from your programs in simple steps. The book begins by describing the basic elements of writing clean code and how it plays an important role in Python programming. To convert the Line class above to a dataclass, convert all of the fields to class attributes and ensure they have type annotations: You can then create an instance of the Line type with the same arguments as before, with the same fields, and even .__str__(), .__repr__(), and .__eq__() are implemented: Dataclasses are a great way to reduce code with a single import that’s already available in the standard library. Ideally, that test suite should be mostly automated, so that as you make changes, you see the impact on the user and address it quickly. If you’re writing code for NASA’s jet propulsion laboratory (literally rocket science), then it’s going to be complicated. Python Code Refactoring Tools If you are using an 'Integrated Development Environment' (IDE) then there is a good chance that this will have some handy tools which you can use. For example, if I made some changes to requests/api.py you will see the impact on the metrics by running wily diff with the file path: In the response, you will see all of the changed metrics, as well as the functions or classes that have changed for cyclomatic complexity: The diff command can be paired with a tool called pre-commit. best-practices The maintainability index brings the McCabe Cyclomatic Complexity and the Halstead Volume measures in a scale roughly between zero and one-hundred.
