Hi,
csv.DictReader uses OrderedDict by default, from Python 3.6.
But it doesn't make sense anymore, like namedtuple._asdict().
How about changing default dict type back to regular dict.
Python is widely used for handling learge data. So I think
changing default dict type to OrderedDict was perfo

Hi Python community folk!
As we've done for the past many years, Python is hoping to participate
in Google Summer of Code. This is a neat program where students write
code over the (northern hemisphere) summer under the tutelage of open
source mentors and get paid: we provide the project ideas, m

Now that regular dicts are ordered and compact, it makes more sense for the
_asdict() method to create a regular dict (as it did in its early days) rather
than an OrderedDict. The regular dict is much smaller, much faster, and has a
much cleaner looking repr. It would also help namedtuple() st

Hello,
I'm sorry for posting here and not to python-announce, somehow I think
(perhaps naively) that it may be of interest to people who are
interested in Python development. At the very least, creation of the
original package is (very likely, I didn't trace up to that) was
discussed on python-dev
