>>> from deepdiff import DeepDiff # For Deep Difference of 2 objects
>>> from deepdiff import DeepSearch # For finding if item exists in an objectIn addition to the 2 objects being compared:
int, string, dictionary, list, tuple, set, frozenset, OrderedDict, NamedTuple and custom objects!
Sometimes you don't care about the order of objects when comparing them. In those cases, you can set ignore_order=True. However this flag won't report the repetitions to you. You need to additionally enable report_report_repetition=True for getting a report of repetitions.
>>> t1 = {1:1, 2:2, 3:3, 4:{"a":"hello", "b":[1, 2, 3]}}
>>> t2 = {1:1, 2:2, 3:3, 4:{"a":"hello", "b":[1, 3, 2, 3]}}
>>> ddiff = DeepDiff(t1, t2, ignore_order=True)
>>> print (ddiff)
{}This flag ONLY works when ignoring order is enabled. Note that this feature is experimental.

t2 = [4, 4, 1]
ddiff = DeepDiff(t1, t2, ignore_order=True, report_repetition=True)
print(ddiff)which will print you:

- Verbose level 0: won't report values when type changed. Example
- Verbose level 1: default
- Verbose level 2: will report values when custom objects or dictionaries have items added or removed. Example
(New in v2-1-0)
Tip: Take a look at grep which gives you a new interface for DeepSearch!
DeepDiff comes with a utility to find the path to the item you are looking for. It is called DeepSearch and it has a similar interface to DeepDiff.
Let's say you have a huge nested object and want to see if any item with the word somewhere exists in it.
from deepdiff import DeepSearch
obj = {"long": "somewhere", "string": 2, 0: 0, "somewhere": "around"}
ds = DeepSearch(obj, item, verbose_level=2)
print(ds)Which will print:
{'matched_paths': {"root['somewhere']": "around"},
'matched_values': {"root['long']": "somewhere"}}Tip: An interesting use case is to search inside locals() when doing pdb.
(New in v3-2-0)
Grep is another interface for DeepSearch. Just grep through your objects as you would in shell!
from deepdiff import grep
obj = {"long": "somewhere", "string": 2, 0: 0, "somewhere": "around"}
ds = obj | grep(item)
print(ds)Which will print:
{'matched_paths': {"root['somewhere']"},
'matched_values': {"root['long']"}}And you can pass all the same kwargs as DeepSearch to grep too:
>>> obj | grep(item, verbose_level=2)
{'matched_paths': {"root['somewhere']": 'around'}, 'matched_values': {"root['long']": 'somewhere'}}result is the output of the function that is being tests.
expected is the expected output of the function.
assertEqual(DeepDiff(result, expected), {})Unlike Json Patch which is designed only for Json objects, DeepDiff is designed specifically for almost all Python types. In addition to that, DeepDiff checks for type changes and attribute value changes that Json Patch does not cover since there are no such things in Json. Last but not least, DeepDiff gives you the exact path of the item(s) that were changed in Python syntax.
Example in Json Patch for replacing:
{ "op": "replace", "path": "/a/b/c", "value": 42 }
Example in DeepDiff for the same operation:
>>> item1 = {'a':{'b':{'c':'foo'}}}
>>> item2 = {'a':{'b':{'c':42}}}
>>> DeepDiff(item1, item2)
{'type_changes': {"root['a']['b']['c']": {'old_type': <type 'str'>, 'new_value': 42, 'old_value': 'foo', 'new_type': <type 'int'>}}}Starting with DeepDiff v 3, there are two different views into your diffed data: text view (original) and tree view (new).
Text view is the original and currently the default view of DeepDiff.
It is called text view because the results contain texts that represent the path to the data:
Example of using the text view.
>>> from deepdiff import DeepDiff
>>> t1 = {1:1, 3:3, 4:4}
>>> t2 = {1:1, 3:3, 5:5, 6:6}
>>> ddiff = DeepDiff(t1, t2)
>>> print(ddiff)
{'dictionary_item_added': {'root[5]', 'root[6]'}, 'dictionary_item_removed': {'root[4]'}}So for example ddiff['dictionary_item_removed'] is a set if strings thus this is called the text view.
The following examples are using the *default text view.*
The Tree View is introduced in DeepDiff v3
and provides traversing capabilities through your diffed data and more!
Read more about the Tree View at the bottom of this page.

{}All the examples for the text view work for the tree view too. You just need to set view='tree' to get it in tree form.
Starting the version v3 You can choose the view into the deepdiff results. The tree view provides you with tree objects that you can traverse through to find the parents of the objects that are diffed and the actual objects that are being diffed.
This view is very useful when dealing with nested objects. Note that tree view always returns results in the form of Python sets.
You can traverse through the tree elements!
The Tree view is just a different representation of the diffed data.
Behind the scene, DeepDiff creates the tree view first and then converts it to textual representation for the text view.

+---------------------------------------------------------------+
- up - Move up to the parent node
- down - Move down to the child node
- path() - Get the path to the current node
- t1 - The first item in the current node that is being diffed
- t2 - The second item in the current node that is being diffed
- additional - Additional information about the node i.e. repetition
- repetition - Shortcut to get the repetition report
The tree view allows you to have more than mere textual representaion of the diffed objects. It gives you the actual objects (t1, t2) throughout the tree of parents and children.
The Tree View is introduced in DeepDiff v3
Set view='tree' in order to use this view.
