Memoiz

Introduction

Memoiz provides a function decorator that adds memoization to a function or method. It makes reasonable assumptions about how and if to cache the return value of a function or method based on the arguments passed to the callable.

 

Features

  • Use the Memoiz decorator on functions and methods.
  • A thread-safe cache.
  • Call your function or method with any number of arguments or keyword arguments.
  • Support for parameter and return type hints.
  • Handles circular references in dictionaries, lists, sets, and tuples.
  • Support for common unhashable types (e.g., dict, list, set).
  • Selective cache entry removal.

Flatten It uses iteration (no recursion) to flatten iterables into a dictionary where each key is a reference path and each value is the value at the respective path.  This simple flattening algorithm has been used for diffing deeply nested JSON structures and for transforming hierarchical data into a tabular data model.
