ntuplelike

ntuplelike is a lightweight Python library designed to provide a simple, immutable sequence type that mimics the behavior of a native tuple. The core object, often referenced as ntuple, supports indexing, slicing, iteration, length queries, and equality checks, offering a convenient alternative when a fixed-size, ordered collection is required but a full tuple is either too restrictive or inconvenient in a particular context. Unlike the built‑in tuple, ntuple instances can be constructed from a variety of iterable sources—including lists, NumPy arrays, pandas Series, and other sequence types—without the programmer needing to perform explicit conversions or copying.

The library is built with compatibility for Python 3.8 and later, and it is distributed under an open‑source license that encourages community contributions. The ntuplelike package primarily serves the data‑science community, where it is often employed for lightweight record representation, configuration containers, or as a drop‑in replacement in legacy code that expects tuple semantics. Its minimal footprint makes it suitable for environments with constrained resources or for rapid prototyping where full object serialization or more complex data structures would be overkill.

Documentation for ntuplelike includes usage examples that demonstrate the conversion of standard lists into ntuple objects, the use of ntuple instances in function arguments, and the equality semantics that are essential for testing and caching scenarios. The project is hosted on GitHub, where contributors can submit pull requests and issue bug reports, ensuring that the library remains current with evolving Python best practices.
