Advanced Python Features
Python is one of the most widely adopted programming languages in the world. Yet, because of it’s ease and simplicity to just “get something working”, it’s also one of the most underappreciated. If you search for Top 10 Advanced Python Tricks on Google or any other search engine, you’ll find tons of blogs or LinkedIn articles going over trivial (but still useful) things like generators or tuples. However, as someone who’s written Python for the past 12 years, I’ve come across a lot of really interesting, underrated, unique, or (as some might say) “un-pythonic” tricks to really level up what Python can do.
Moreover, it enhances performance by avoiding the immediate computation of annotations that might not be used, and maintains full semantic information, supporting introspection and runtime type-checking tools. Under the hood, Python classes store instance attributes in an internal dictionary called__dict__, meaning a hash table lookup is required each time you want to access a value. - Tim Peters But if you are that 1% which has a unique enough problem that only metaclasses can solve, they are a powerful tool that lets you tinker with the internals of the Python object system.
