If both dictionaries have common keys, then the final output using this method will contain the value of the second dictionary. Here, we also use the for loop to iterate through the dictionary items and merge them to get the final output. Finally we merge the two dictionaries using the | operator available for the dictionaries. We can combine two dictionaries in python using dictionary comprehension. Using a for loop Using the dict.update () method Using the operator Using the (Union) operator (for Python 3.9 and above) Let's explore each way one after another. Dictionaries are a convenient way to store data in Python. Here’s what you’ll learn in this tutorial: You’ll cover the basic characteristics of Python dictionaries and learn how to access and manage dictionary data. This article covers all the methods to merge dictionaries in Python. In this approach we design a for loop to check for the presence of the value of the key in both the dictionaries and then add them. Python provides another composite data type called a dictionary, which is similar to a list in that it is a collection of objects. In this article we will see such two dictionaries getting added. Lets say you have two (or more) dictionaries in Python and you want to unite them into a single dictionary containing the keys and values from both of the. When analyzing data with python we come across situations when we have to merge two dictionaries in such a way that we add the values of those elements whose keys have equal values.
