namedtuplePerson

namedtuplePerson is a simple, immutable data structure in Python designed to represent a person record using the namedtuple factory from the collections module. Namedtuples create lightweight, readable classes with named fields, making small records easier to work with than plain tuples.

Typically, a namedtuple type is defined and then instantiated. For example, one might define Person = namedtuple('Person', ['name','age','email']), and then create namedtuplePerson = Person('Alice', 30, '[email protected]'). The resulting object supports attribute access (namedtuplePerson.name) as well as index-based access (namedtuplePerson[0]).

Key features include the ability to access fields by name or index, and several helper methods. _asdict() converts the instance to a dict-like mapping of field names to values; _replace(**kw) returns a new instance with some fields modified, preserving the original object; and _fields lists the field names. The type itself is a subclass of tuple, which contributes to its immutability and memory efficiency.

Benefits of namedtuplePerson include its immutability, compact memory footprint, and clear, self-documenting code for simple data records. It is well suited for lightweight data transmission, record-like structures, or configurations where behavior is minimal.

Limitations include lack of built-in support for complex behavior and defaults without extra boilerplate. They are less flexible than full classes or dataclasses for larger structures. For more complex needs, using a dataclass (with frozen=True) or a regular class is often preferable. See also: Python collections module, dataclasses.
