[New-bugs-announce] [issue38996] introduction of default values for collection.namedtuple

[Arno-Can Uestuensoez]

New submission from Arno-Can Uestuensoez <acue.opensource at gmail.com>:

Hello,
I had the requirement to make excessive use of named tuples in an extended way. The applications are variable data sets with optional items. Typical in protocol dat a units, or e.g. mixed abstract filesystem types for heterogeneous file system types including URL and UNC.

As I saw the required changes are a couple of lines which I see as harmless. The implementation is available for Python2.7 and Python3.5+ in the project namedtupledefs, which is the patched code extracted from the *collections*.

The detailed descriptions for both versions are available at:
Python3: https://namedtupledefs3.sourceforge.io/
Python3: https://namedtupledefs.sourceforge.io/
Python2: https://namedtupledefs2.sourceforge.io/

Checked in PyPi + Sourceforge + github - the links are in the documents.

https://github.com/ArnoCan/namedtupledefs2/
https://github.com/ArnoCan/namedtupledefs/

https://pypi.org/project/namedtupledefs[23]/

My proposal is to introduce the changes. It would be great for Python2.7 too, before the EOL.
