Modules

  • DeepDiff: Deep Difference of dictionaries, iterables, strings, and ANY other object.
  • DeepSearch: Search for objects within other objects.
  • DeepHash: Hash any object based on their content.
  • Delta: Store the difference of objects and apply them to other objects.

  • commandline: Use DeepDiff from commandline.

Tested on Python 3.8+ and PyPy3.

What is new?

Please check the ChangeLog file for the detailed information.

DeepDiff 8-0-1

  • Bugfix. Numpy should be optional.

DeepDiff 8-0-0

With the introduction of threshold_to_diff_deeper, the values returned are different than in previous versions of DeepDiff. You can still get the older values by setting threshold_to_diff_deeper=0. However to signify that enough has changed in this release that the users need to update the parameters passed to DeepDiff, we will be doing a major version update.

  • use_enum_value=True makes it so when diffing enum, we use the enum's value. It makes it so comparing an enum to a string or any other value is not reported as a type change.
  • threshold_to_diff_deeper=float is a number between 0 and 1. When comparing dictionaries that have a small intersection of keys, we will report the dictionary as a new_value instead of reporting individual keys changed. If you set it to zero, you get the same results as DeepDiff 7.0.1 and earlier, which means this feature is disabled. The new default is 0.33 which means if less that one third of keys between dictionaries intersect, report it as a new object.
  • Deprecated ordered-set and switched to orderly-set. The ordered-set package was not being maintained anymore and starting Python 3.6, there were better options for sets that ordered. I forked one of the new implementations, modified it, and published it as orderly-set.
  • Added use_log_scale:bool and log_scale_similarity_threshold:float. They can be used to ignore small changes in numbers by comparing their differences in logarithmic space. This is different than ignoring the difference based on significant digits.
  • json serialization of reversed lists.
  • Fix for iterable moved items when iterable_compare_func is used.
  • Pandas and Polars support.

DeepDiff 7-0-1

  • Fixes the translation between Difflib opcodes and Delta flat rows.

DeepDiff 7-0-0

  • DeepDiff 7 comes with an improved delta object. Delta to flat dictionaries have undergone a major change. We have also introduced Delta serialize to flat rows.
  • Subtracting delta objects have dramatically improved at the cost of holding more metadata about the original objects.
  • When verbose=2, and the "path" of an item has changed in a report between t1 and t2, we include it as new_path.
  • path(use_t2=True) returns the correct path to t2 in any reported change in the tree view
  • Python 3.7 support is dropped and Python 3.12 is officially supported.

DeepDiff 6-7-1

DeepDiff 6-7-0

  • Delta can be subtracted from other objects now.
  • verify_symmetry is deprecated. Use bidirectional instead.
  • always_include_values flag in Delta can be enabled to include values in the delta for every change.
  • Fix for Delta.add breaks with esoteric dict keys.
  • You can load a delta from the list of flat dictionaries.

DeepDiff 6-6-1

Installation

Install from PyPi:

pip install deepdiff

If you want to use DeepDiff from commandline:

pip install "deepdiff[cli]"

If you want to improve the performance of DeepDiff with certain functionalities such as improved json serialization:

A message from Sep, the creator of DeepDiff

👋 Hi there,

Thank you for using DeepDiff! As an engineer, I understand the frustration of wrestling with unruly data in pipelines. That's why I developed a new tool - Qluster to empower non-engineers to control and resolve data issues at scale autonomously and stop bugging the engineers! 🛠️

If you are going through this pain now, I would love to give you early access to Qluster and get your feedback.

Survey

:mega: Please fill out our fast 5-question survey so that we can learn how & why you use DeepDiff, and what improvements we should make. Thank you! :dancers:

Contribute

  1. Please make your PR against the dev branch
  2. Please make sure that your PR has tests. Since DeepDiff is used in many sensitive data driven projects, we strive to maintain around 100% test coverage on the code.

Please run pytest --cov=deepdiff --runslow to see the coverage report. Note that the --runslow flag will run some slow tests too. In most cases you only want to run the fast tests which so you wont add the --runslow flag.

Or to see a more user friendly version, please run: pytest --cov=deepdiff --cov-report term-missing --runslow.

Thank you!
