List Comprehension is also a method where you can compare dictionaries. The equal “ =” operator is the straightforward and easy way to know if the two dictionaries are the same or not.
#COMPARE TWO LIST OF DICTIONARIES PYTHON HOW TO#
In this article, we saw how to do a comparison of two dictionaries by using the equal “ =” operator, list comprehension, and using DeepDiff() function. then we are getting the changed values in dictionary a, the name key’s value was Dhushi, but now it has changed to Praj in dictionary b, similarly with the key age.
lastly, the important part, we provided our two dictionaries to DeepdDiff() function where we are comparing dictionary b from a so the result produced over here is like that we have added an additional item or a new key-value pair which is the key,.secondly, we are getting the value False because obviously, the dictionaries are not the same, and as well they are not equal.firstly, we are getting the value False because the lengths of dictionaries a and b are different, which is right because dictionary b has one additional key-value pair.
#COMPARE TWO LIST OF DICTIONARIES PYTHON CODE#
A non-exhaustive list can be found here on this post here on Code Review Meta. There is good tool support for style and also static code checking in Python. Fortunately you don't have to remember all those rules. Let’s look at the result produced through the above code. A core takeaway of the read should be, that in Python lowercasewithunderscores is the preferred way to name variables and functions. Lists of different lengths are never equal. lastly, we are using DeepDiff() function for the comparison, and let’s look at the result down. When you compare lists for equality, you’re checking whether the lists are the same length and whether each item in the list is equal.Then we check, whether the two dictionaries are the same or not.firstly, we print whether the length of the two dictionaries are the same or not by using len() function.declared two different dictionaries of different lengths in the a and b variables.It will recursively look for all the changes. import DeepDiff from deepdiff so we can get the function DeepDiff which will help us find the difference between dictionaries, iterables, strings, and other objects.Whereas the other 2 method have time complexity of O (n). The time complexity of 1 st approach is O (1) as it uses simple comparison. In the final method we used the list comprehension method of python to iterate over key value pair of one dictionary and check the values for the keys in both dictionaries and compared them. The second method involved use of iteration to check each and every key value pair of both the dictionaries. The first method involved use of equality operator ( =). We came across 3 different methods to compare 2 dictionaries. We also learnt how we can compare 2 given dictionaries. In this article, we came to know about dictionaries in python, where we can use dictionaries. The output for the above code will be as follows − dict1 and dict2 are not equal
In Python, a dictionary can be created by placing a sequence of elements within curly Īns = all ( dict2.get (key) = value for key, value in ems() ) We will go over the syntax for comparing dictionary elements and will provide examples of how to do so. In this method, we will compare the elements of two dictionaries one by one by iterating over the length of one dictionary and checking the key and values for every iteration with the corresponding key and value pair in other dictionary. In this article, we will be discussing how to compare elements in two dictionaries in Python. Dictionaries are a powerful data type in Python that allow you to store data as key-value pairs.
