DeepDiff 5.8.1 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

New In DeepDiff 5-8-1

DeepDiff 5-8-1 includes bug fixes: - Fixed test suite for 32bit systems (https://github.com/seperman/deepdiff/issues/302) by Louis-Philippe Véronneau - Fixed the issue when using ignore_order=True and group_by simultaneously - Added the support for diffing object properties (@property) (https://github.com/seperman/deepdiff/issues/312) - Better support of diffing private variables

New In DeepDiff 5-8-0

DeepDiff 5-8-0 includes bug fixes and improvements:

  • Fixed the bug with delta randomly not producing the same results when ignore_order=True

  • Display detailed pretty when verbose

  • Allow ordered-set version 4.1.x

  • Removing extra logging when key is not found in DeepHash

  • Fixed error when comparing non-utf8 byte strings with ignore_order=True

  • Fixed Tests fail after 2022-05-14

  • Fixed TypeError is thrown when comparing bool and str

Installation

Install from PyPi:

pip install deepdiff

If you want to use DeepDiff from commandline:

pip install "deepdiff[cli]"

Read about DeepDiff optimizations at Optimizations

>>> 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
Note: if you want to use DeepDiff via commandline, make sure to run::

pip install “deepdiff[cli]”

Then you can access the commands via:

  • DeepDiff

$ deep diff --help

  • Delta

$ deep patch --help

  • grep

$ deep grep --help

  • extract

$ deep extract --help
