Eric V. Smith added the comment: I agree with Steven, but since I have this typed up I'll post it here. Yes, iterability is another namedtuple feature. Although that would actually be easy to add to dataclasses, so I didn't mention it. I don't really see the point of combining them, except f

Steven D'Aprano added the comment: Hi Pavel. Thank you for your submission, but your request is based on a serious misunderstanding of the koan from PEP 20. You might consider that Python has, for example, both for loops and while loops; it has lists and tuples; it has ints and floats and D

[issue44768] dataclasses.dataclass and collections.namedtuple do the same thing

New submission from pavel-lexyr : PEP 20 states: > There should be one-- and preferably only one --obvious way to do it. As of right now, two very similar constructions for making a lightweight dataclass exist in Python. collections.namedtuple is one of them. dataclasses.dataclass is the oth
