Magic Methods (Dunder Methods)

Magic methods let you define how objects of your class behave with Python's built-in operations. Some important ones include:

• __str__ and __repr__ - Control how your object is printed

• __len__ - Define what len(object) returns

• __add__, __sub__, etc. - Enable math operators like + and -

• __eq__, __lt__, etc. - Enable comparison operators

• __getitem__ and __setitem__ - Make your object indexable like a list

• __call__ - Make your object callable like a function
