Write Simple Code in Python by Managing Types and Using Built-in Libraries
Writing simple, clean code depends on type precision: a function should require exactly the information it needs as input, accept the most general type that supports its use, and return a specific, predictable type. Violating this produces needless coupling, extra code, and complexity, as expressed by the Law of Demeter (principle of least knowledge) and the principle of generic arguments with specific return values. This belongs to software design and type-annotated programming, where types serve as contracts that govern coupling, reusability, and clarity.
