Verified usage

Verified import paths — ran on the pinned version, not inferred.

recursive_update

✓ from dict_recursive_update import recursive_update

✗ from dict_recursive_update.recursive_update import recursive_update

Wrong path: the function is directly in the package, not in a submodule.

Deep merge d2 into d1, modifying a copy to avoid side effects.

from dict_recursive_update import recursive_update d1 = {'a': 1, 'b': {'c': 2}} d2 = {'b': {'d': 3}, 'e': 4} merged = recursive_update(d1.copy(), d2) print(merged)

Debug

Known issues

gotchaThe function mutates the first argument in-place. Always pass a copy if you want to preserve the original.

fix

Use recursive_update(d1.copy(), d2) instead of recursive_update(d1, d2).

affects: all

gotchaOnly works with dict-like objects. Passing lists or other iterables will raise an AttributeError.

fix

Ensure all nested structures are dictionaries or implement the dict interface.

affects: all

deprecatedThe package has no active development since 2019. Consider alternatives like deepmerge or dictdiffer for ongoing maintenance.

fix

Migrate to deepmerge (pip install deepmerge) for better features and support.

affects: 1.0.1

Errors

Common errors & fixes

AttributeError: 'list' object has no attribute 'keys'

Attempting to use recursive_update on a dictionary that contains lists as values.

fix

Ensure that nested values are dictionaries, not lists. If you need to merge lists, implement a custom strategy.

ImportError: cannot import name 'recursive_update' from 'dict_recursive_update'

Wrong import path; the function is not in a submodule.

fix

Use: from dict_recursive_update import recursive_update
