DeepDiff 6.2.0 documentation!

DeepDiff Overview

The DeepDiff library includes the following modules:

  • DeepDiff For Deep Difference of 2 objects. DeepDiff

    It return the deep Difference of python objects. It can also be used to take the distance between objects. Deep Distance

  • DeepSearch Search for objects within other objects. DeepSearch

  • DeepHash Hash any object based on their content even if they are not “hashable” in Python’s eyes. DeepHash

  • Delta Delta of objects that can be applied to other objects. Imagine git commits but for structured data. Delta

  • Extract For extracting a path from an object Extract

  • Commandline Most of the above functionality is also available via the commandline module Command Line

What is New

DeepDiff 6-2-0

  • Major improvement in the diff report for lists when items are all hashable and the order of items is important.

DeepDiff 6-1-0

  • DeepDiff.affected_paths can be used to get the list of all paths where a change, addition, or deletion was reported for.

  • DeepDiff.affected_root_keys can be used to get the list of all paths where a change, addition, or deletion was reported for.

  • Bugfix: ValueError when using Decimal 0.x #339 by Enric Pou

  • Serialization of UUID

DeepDiff 6-0-0

  • Exclude Obj Callback Strict parameter is added to DeepDiff by Mikhail Khviyuzov mskhviyu.

  • A fix for diffing using iterable_compare_func with nested objects by dtorres-sf who originally contributed this feature.

  • Temporarily we are publishing DeepDiff under DeepDiff6 on pypi until further notice.

Note: There are no breaking changes in DeepDiff 6 compared to the latest DeepDiff 5 releases.

Install from PyPi:

pip install deepdiff6

If you want to use DeepDiff from commandline:

pip install "deepdiff6[cli]"

Prior to DeepDiff 6, it was published under DeepDiff name on pypi.

DeepDiff 6 is being published under DeepDiff6 package name on Pypi temporarily until further notice.

>>> from deepdiff import DeepDiff  # For Deep Difference of 2 objects
>>> from deepdiff import grep, DeepSearch  # For finding if item exists in an object
>>> from deepdiff import DeepHash  # For hashing objects based on their contents
>>> from deepdiff import Delta  # For creating delta of objects that can be applied later to other objects.
>>> from deepdiff import extract  # For extracting a path from an object


if you want to use DeepDiff via commandline, make sure to run:: pip install “deepdiff6[cli]”

Then you can access the commands via:

  • DeepDiff

$ deep diff --help
  • Delta

$ deep patch --help
  • grep

$ deep grep --help
  • extract

$ deep extract --help
