Dictionary update method in Python 3 4

Title: A Comprehensive Guide to the Dictionary Update Method in Python 3.4
Introduction:
Python dictionaries are versatile data structures that allow you to store and manipulate key-value pairs. The update method is a handy feature introduced in Python 3.4 that simplifies the process of merging or updating one dictionary with the contents of another. This tutorial will walk you through the basics of the update method, its syntax, and provide practical code examples to illustrate its usage.
The update method in Python dictionaries is used to merge the keys and values of one dictionary into another. It takes another dictionary or an iterable of key-value pairs as its argument and adds them to the calling dictionary. If there are any common keys between the two dictionaries, the values from the argument dictionary overwrite the values in the calling dictionary.
Output:
In this example, dict2 is merged into dict1. The common key 'b' is updated with the value from dict2.
Output:
In this example, an iterable containing key-value pairs is used to update the original dictionary.
Output:
Here, the update method is used with keyword arguments (**kwargs) to add new key-value pairs to the dictionary.
The update method in Python 3.4 provides a convenient way to merge dictionaries, making it a valuable tool for dictionary manipulation. Whether you're combining dictionaries or adding new key-value pairs, the update method simplifies the process and enhances the flexibility of working with dictionaries in your Python programs.
