maybe a value. definitely a duck.

kamokamo brings Rust’s Option, Result, and iterator vocabulary to Python. it requires Python 3.14+ and has no runtime dependencies.

Option holds a value or represents absence. Result holds a successful value or an expected error. Iter builds lazy pipelines, and Peekable adds one item of lookahead.

• tutorials: build a small program, step by step.

• how-to guides: handle missing values, errors, and streams.

• API reference: look up a type, signature, or behavior.

• explanation: understand the choices behind the API.

a duck, perhaps

鴨 (kamo) means “duck”; かも expresses “maybe.” 鴨かも brings them together: Python’s duck typing meets Maybe types. sometimes there is Some. sometimes there is Nothing.
