Interesting Python features that I've come across in my career

Python is a widely used programming language known for its simplicity, but it can also be misunderstood. Edward Li's blog post highlights 14 advanced Python features that can enhance programming skills. These features include typing overloads, which allow defining multiple signatures for a function, and keyword-only and positional-only arguments that help control how parameters are passed. Future annotations improve type hinting by postponing evaluation until needed, addressing issues with forward references. Generics, introduced in Python 3.12, offer a new syntax for type parameters, enhancing type safety and flexibility. Protocols enable duck typing, allowing functions to accept any object that implements a specific method, regardless of its actual type. Other features discussed include context managers, structural pattern matching, Python slots, advanced f-string formatting, caching with lru_cache, Python futures, proxy properties, and metaclasses. Each feature is accompanied by examples and additional resources for further exploration. This compilation serves as a valuable resource for developers looking to deepen their understanding of Python's capabilities.

Very cool! Had zero idea about enforcing keyword/positional and function overloads (definitely have missed those from Java in the past).

Thank you for making that list, these are really interesting indeed.
