Namedtuple
Namedtuple is a factory function in Python's collections module that creates tuple subclasses with named fields, allowing access to elements by attribute names instead of integer indices. It combines the immutability and memory efficiency of tuples with the readability of classes, making data structures more self-documenting and easier to use. Namedtuples are commonly used for lightweight object representations, such as records or simple data containers, without the overhead of full class definitions.
Developers should learn Namedtuples when working with structured data that requires immutability and clear field names, such as configuration settings, data points in analytics, or return values from functions. They are particularly useful in scenarios where you need tuple-like performance but want to avoid the confusion of index-based access, improving code readability and reducing errors. Namedtuples are also a good choice for simple data transfer objects or when interfacing with APIs that expect tuple-like structures.
