Now, let’s see how we can use a list comprehension to find the differences between two lists: list1 = For a refresher on for-loops, check out my post here and my video tutorial here: In order to calculate a repetitive list difference in Python, we can use a for-loop. Calculate List Difference with Duplicate Items with a For Loop
Now, were we to calculate non-repetitve list differences, both differences would simply be.
However, were we do to the same between list1b and list2, we would return. Between list1 and list2, we would return. Were we to calculate a duplicate list difference: However, we also have list1b that contains two 3’s. We have lists list1 and list2 which contain only unique items. Now, to understand better, let’s look at three different lists: list1 = If you’re looking to find the list of items that exist in either list but not both, check out the section on finding Python symmetrical difference. If we were to calculate the difference between list2 and list1, we would find that list2 contains, while list1 doesn’t. If we were to calculate the difference between list1 and list2, we would find that list1 contains, while list2 doesn’t. Say we have two different lists: list1 = Whether repetition matters: since lists can contain duplicate values, some methods will work better for this. The comparison ordering matters: if you want to find the items in one list but not in the other, you need to use that are your comparator. There are two main things to understand here: Python list difference refers to finding the items that exist in one list, but not in the other. #COMPARE TWO LIST OF DICTIONARIES PYTHON HOW TO#
How to calculate Python Symmetrical List Difference?. Calculate List Difference with the Set. Python List Difference with Set Subtraction. Calculate List Difference with a List Comprehension. Calculate List Difference with Duplicate Items with a For Loop. If this condition is found true, add that key-value pair to the common dictionary variable. Also, check if the value from both dictionaries is the same for the same key. In each iteration of For Loop check if the key from the second dictionary exists in the first dictionary. Create a blank dictionary that will contain the common key-value pairs. Create two dictionaries that contain some properties. We will be using Python For loop to the common key-value pairs. We can get the common key-value pairs from two dictionaries and check if those are equal or not. Output Get common key-value pairs from two dictionaries Syntax DeepDiff(dict1, dict2) from deepdiff import DeepDiff It will return the dictionary that will contain the information of the difference between the dictionaries. We will be using the DeepDiff() function from the deepdiff module to compare the dictionaries. #COMPARE TWO LIST OF DICTIONARIES PYTHON INSTALL#
We can install the deepdiff module using the below command in your project. You can install the Python module deepdiff in your project and check the differences between the two dictionaries.
Print message - " The dictionaries are equal" if the dictionaries are equal.Ĭompare dictionaries using the deepdiff python module. Using dict2 = dict4 code, we are comparing two dictionaries. This will return True if all the dictionaries are equal. 
#COMPARE TWO LIST OF DICTIONARIES PYTHON CODE#
Using dict1 = dict2 = dict3 = dict4 code syntax we are comparing all the dictionaries.Created four dictionaries(dict1, dict2, dict3, dict4) using different methods.
