Merging dictionaries is a common operation in Python, especially when you have two dictionaries with overlapping keys and you want to combine their values. In this tutorial, we'll explore different methods to merge two dictionaries with the same keys.
The update() method is a simple and effective way to merge dictionaries. It updates the dictionary with the key-value pairs from another dictionary.
Output:
In this example, the update() method is used to merge dict2 into dict1. If there are common keys, the values from dict2 overwrite the values from dict1.
You can use the ** unpacking operator to merge dictionaries in a concise way.
Output:
Here, the ** unpacking operator is used to create a new dictionary by unpacking the key-value pairs from both dict1 and dict2.
You can use the dict() constructor and the items() method to achieve dictionary merging.
Output:
This method involves converting the key-value pairs of both dictionaries into lists and then creating a new dictionary from the merged lists.
Choose the method that best fits your use case. The update() method is often the most straightforward, but the other methods offer flexibility depending on your specific needs.
