PYTHON DEEPOPS MODULE

This module contains some functions for performing "deep" operations on standard Python "compound" data structures - lists/sets/dictionaries:

• deepmerge() - merges two compound structures, including all sub-items, e.g. items to lists and sets, missing keys/items to dictionaries, optionally replacing clashing simple types.
• deepremoveitems() - removes items (simple types, or whole compound structures) from within another compound data structure.
• deepfilter() - returns the part of one compound structure that is matched by the other: essentially the opposite of deepremoveitems().
• deepdiff() - compares two compound structures and returns a tuple of items to be removed and items to be updated: these could be passed to deepremoveitems() and deepmerge(), respectively, to transform one into the other (although note that they would need to be deepcopy()ed first).
• deepsetdefault() - similar to dict.setdefault() except that it can set the default at arbitrarily deep paths into a dictionary.
• deepget() - similar to dict.get() but can copy with arbitrarily deep paths into an indexable structure.

The module was developed and used under Python 3.4-3.7 but seems to work OK in basic testing under 2.7.
