Project description

A Python module who does recursive update work on 2 dicts.



pip install dict-recursive-update


>>> from dict_recursive_update import recursive_update

>>> recursive_update({'a': {'b': 2}}, {'a': {'b': 3, 'd': 4}, 'e': 5})
{'a': {'b': 3, 'd': 4}, 'e': 5}

>>> recursive_update('a', 'b')
Traceback (most recent call last):
TypeError: Params of recursive_update should be dicts

>>> recursive_update({'a': [1]}, {'a': [2], 'c': {'d': {'c': 3}}})
{'a': [2], 'c': {'d': {'c': 3}}}

>>> recursive_update({'a': {'c': 1, 'd': {}}, 'b': 4}, {'b': 5})
{'a': {'c': 1, 'd': {}}, 'b': 5}

>>> recursive_update({'a': {'c': 1, 'd': {}}, 'b': 4}, {'a': 2})
{'a': 2, 'b': 4}


This is originally designed for merge multiple configurations in different running environment such as production or stage.

As a node.js developer, package config and lodash are very handy for me. This package is the base of a python-version config package.

In a normal project, there is usually a copy of default configuration, but when we deploy it, some configurations differ from default ones like database address. So a handy configuration-loading package is supposed to load right configurations according to the running environment.
