[New-bugs-announce] [issue40284] Add mapping methods to types.SimpleNamespace

[Raymond Hettinger]

New submission from Raymond Hettinger <raymond.hettinger at gmail.com>:

types.SimpleNamespace() would be much more usable if it were more substitutable for dictionaries.   In particular, it would be wonderful to be able to use object_hook=SimpleNamespace in json.load():

Current:

     catalog = json.load(f)
     print(catalog['clothing']['mens']['shoes']['extra_wide']['quantity'])

Proposed:

     catalog = json.load(f, object_hook=SimpleNamespace)
     print(catalog.clothing.mens.shoes.extra_wide.quantity])
