Python Medium Theory

Common special methods like `str`, `repr`, `len`, `getitem`, and `contains`

Special methods let your objects behave like built-in types in printing, indexing, length checks, and membership operations.

`__str__` is user-friendly output
`__repr__` should be unambiguous
Container protocols come from dunder methods

Iteration, comparison, and callable special methods in Python

Methods like `__iter__`, `__next__`, `__call__`, `__eq__`, `__lt__`, and `__hash__` define how custom objects participate in loops, comparisons, hashing, and callable syntax.

Iterators use `__iter__` and `__next__`
Ordering and equality use rich comparison methods
Hashing must stay consistent with equality
