Keeping this in view, what is function caching in Python?
Function caching allows us to cache the return values of a function depending on the arguments. It can save time when an I/O bound function is periodically called with the same arguments. In Python 3.2+ there is an lru_cache decorator which allows us to quickly cache and uncache the return values of a function.
Also Know, what is the function of caching? A cache's primary purpose is to increase data retrieval performance by reducing the need to access the underlying slower storage layer. Trading off capacity for speed, a cache typically stores a subset of data transiently, in contrast to databases whose data is usually complete and durable.
Keeping this in consideration, does Python have Functools?
The functools module, part of Python's standard Library, provides useful features that make it easier to work with high order functions (a function that returns a function or takes another function as an argument ).
What is cached property in Python?
The @cached_property is a decorator which transforms a method of a class into a property whose value is computed only once and then cached as a normal attribute.
