Answer 1

The pyjq library does something quite similar to this, except you have to explicitly provide a dictionary to be the root, and you have to prefix your strings with a . to refer to whatever dictionary was your root.

python:

import pyjq
d = { 'a' : { 'b' : { 'c' : 'd' } } }
for path in ['.a', '.a.b', '.b.c.d', '.x']:
    print(pyjq.first(path, d))

output:

{'b': {'c': 'd'}}
{'c': 'd'}
None
None
