a toolset to deeply merge python dictionaries.
Project description
A tools to handle merging of nested data structures in python.
Example
Generic Strategy
from deepmerge import always_merger base = {"foo": ["bar"]} next = {"foo": ["baz"]} expected_result = {'foo': ['bar', 'baz']} result = always_merger.merge(base, next) assert expected_result == result
Custom Strategy
from deepmerge import Merger my_merger = Merger( # pass in a list of tuple, with the # strategies you are looking to apply # to each type. [ (list, ["append"]), (dict, ["merge"]), (set, ["union"]) ], # next, choose the fallback strategies, # applied to all other types: ["override"], # finally, choose the strategies in # the case where the types conflict: ["override"] ) base = {"foo": ["bar"]} next = {"bar": "baz"} my_merger.merge(base, next) assert base == {"foo": ["bar"], "bar": "baz"}
You can also pass in your own merge functions, instead of a string.
