How do you implement a case-insensitive (or caseless) dictionary? In this article we explore solutions where we inherit from the built-in dict, the abstract base class MutableMapping from the standard module collections.abc, and the UserDict in the standard module collections.
This is a short and practical tutorial that guides you on how to work with case-insensitive strings in Python and teaches how to use the str.lower, str.upper, and str.casefold methods.
Learn about the dunder method __init__, responsible for initialising class instances.
This is an introduction to dunder methods in Python, to help you understand what they are and what they are for.
