Deep Path Strings

A deep path string is used to access a nested data structure of arbitrary length. Each level is separated by a "." and can be used on both dictionaries and lists. If a "." is contained in one of the dictionary keys, then it can be escaped using "\". For accessing a dictionary key that is a number, it can be wrapped in brackets like "[1]".


>>> data = {'a': {'b': {'c': [0, 0, {'d': [0, {1: 2}]}]}}}
>>> pydash.get(data, 'a.b.c.2.d.1.[1]')

>>> data = {'a': {'b.c.d': 2}}
>>> pydash.get(data, r'a.b\.c\.d')

Pydash’s callback system supports the deep property style callback using deep path strings.
