Installation

$ pip install mergedeep

Usage

merge(destination: MutableMapping, *sources: Mapping, strategy: Strategy = Strategy.REPLACE) -&gt; MutableMapping

Deep merge without mutating the source dicts.

```python3 from mergedeep import merge

a = {"keyA": 1} b = {"keyB": {"sub1": 10}} c = {"keyB":...

AI interpretation — verify before relying

AI-generated interpretation of the package facts above; every digit, version, license, or vulnerability id it cites is grounded in the facts already shown on this page

mergedeep recursively combines multiple dictionaries into a single result, with configurable strategies for handling conflicts between nested keys and different value types.

No runtime dependencies and a pure-Python wheel distribution keep installation friction minimal. However, the package entered dormancy in 2021 with no releases in over five years, so bug fixes or compatibility updates for newer Python versions would require community or maintainer action.

MIT license permits unrestricted use, modification, and distribution in both open-source and commercial contexts with only attribution required.

Usage

pip install mergedeep

from mergedeep import merge

dst = {"a": 1}
src = {"b": {"nested": 2}}
result = merge(dst, src)
print(result)  # {"a": 1, "b": {"nested": 2}}

Requires Python 3.6 or later; package classifiers list support through 3.9 but dormancy since 2021 means untested compatibility with Python 3.10+.

Verdict: mergedeep is a lightweight, dependency-free utility for deep dictionary merging with multiple strategies and no known vulnerabilities. Its dormant maintenance status (last release February 2021) poses a modest risk for future Python compatibility issues, but the narrow scope and stable API make it suitable for projects that can tolerate infrequent updates.

Needs verification

Whether the package has been tested against Python 3.10, 3.11, 3.12, or later versions despite the 2021 release cutoff.
Whether the maintainer or community has plans to resume active maintenance or if the project is considered feature-complete.
