glom

Reminds me of glom[1], another Python library that allows for traversing dicts using dot notation. >>> data = {'a': {'b': {'c': 'd'}}} >>> glom(data, 'a.b.c') 'd' Box uses a slightly different approach. >>> data = Box({'a': {'b': {'c': 'd'}}}) >>> data.a.b.c 'd' I didn't see anything in the README about type inference, which would make the later example more desirable in my opinion. Otherwise I would prefer not to introduce a new container class to my code (Box) if avoidable. [1] https://github.com/mahmoud/glom

This is great recommendation, you can get very far by reading well written code. These have very well written Python, exposing much of the language expressiveness: - https://github.com/python-attrs/attrs - https://github.com/mahmoud/glom - https://github.com/pytoolz/toolz - https://github.com/Suor/funcy - https://github.com/dabeaz/curio ps: dabaez has great educational content on writing idiomatic python, definitely worth checking out An honorable mention of norvig's classic essays, which got me into python while I was in college, over 12y ago: https://norvig.com/spell-correct.html. Aside from reading code, _writing_ something that you know it exist (e.g glom) and then comparing it to how others have done it is also a great learning experience.

The big, classical school of Python definitely prefers top-level functions. Still, I definitely understand that aesthetic, and am on board with not using functools.partial to achieve it. So: https://github.com/mahmoud/glom/issues/14 :)
