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. ![]() I am not able to parse the dictionary if the nesting is not fixed. We also learnt how we can compare 2 given dictionaries. I am trying to find a way to compare two dictionaries without any library but the data is nested and keys are not ordered too.The data is dynamic in nature meaning the the keys in dictionary will change and nesting also. ![]() In this article, we came to know about dictionaries in python, where we can use dictionaries. The simplest technique to check if two or multiple dictionaries are equal is by using the operator in Python. 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() ) Python 3. ![]() akey not in B or A akey B akey -> (This happens only when akey is present in B). Next, find the key akey in A that is the smallest key for which. If they are unequal, then return cmp (len (A), len (B)). You can convert the dicts in the lists to tuples of items first and then use collections.Counter to compare the two lists regardless of order: from collections import Counter def compare (a, b): return Counter (tuple (d.items ()) for d in a) Counter (tuple (d.items ()) for d in b) so that the comparison of the following two lists of dicts. We will go over the syntax for comparing dictionary elements and will provide examples of how to do so. So basically What happens is that to compare dicts A and B, lengths are compared first (equal no problem). The easiest way to compare Python dictionaries is simply to use the same equality operator you use on other Python types. 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. If is it important that the two values being compared are of exactly the same type, rather than just being equal as far as Python is.
