Python’s object-oriented nature makes inheritance a go-to technique for code reuse and extension. But, as with great power comes great responsibility, there are right and wrong ways to leverage inheritance. Following best practices saves headaches and boosts maintainability, extensibility, and readability.

Read on to learn top strategies and techniques for mastering effective inheritance in Python.

Prefer Composition Over Inheritance

Although inheritance seems natural, it isn’t always the ideal choice. Often, favoring composition leads to better design, increased modularity, and looser coupling. Use inheritance sparingly, reserving it for true IS-A relationships. If you find yourself writing awkward or complicated inheritance chains, stop and reevaluate if composition would yield superior results.

Limit Inheritance Hierarchy Depth

Deep inheritance hierarchies obscure code flow, complicate debugging, and increase cognitive load. Stick to flat or moderately nested hierarchies to…
