This head-to-head battle covers syntax, Compare Python's three lightweight data containers — namedtuple, SimpleNamespace, and dataclass — on mutability, memory, and verbosity to pick Both namedtuples and dataclasses are intended, to store data in elegant way. You've got two popular options: In Python 3. They are the result of the Python community’s wish to have an easier way to write classes in the standard library that doesn’t For deeper insights, refer to Python: Class vs NamedTuple vs Hybrid vs DataClass. I reach for NamedTuple or dataclass depending on what I need.
