Certainly! Adding an item to the beginning of a dictionary in Python involves using the update() method along with the {} syntax to create a new dictionary with the desired key-value pair at the beginning. Here's a step-by-step tutorial with a code example:
In Python, dictionaries are unordered collections of items. Each item in a dictionary has a key-value pair, where the key is unique.
Start by creating a dictionary. For the purpose of this tutorial, let's create a sample dictionary.
Define a new key-value pair that you want to add to the beginning of the dictionary.
To add the new key-value pair to the beginning of the dictionary, create a new dictionary using {} and use the update() method.
Here, {new_key: new_value} creates a new dictionary with the new key-value pair, and **original_dict unpacks the original dictionary into the new one, effectively adding the new pair at the beginning.
Print the updated dictionary to verify that the new key-value pair has been added to the beginning.
This tutorial provides a simple and effective way to add an item to the beginning of a dictionary in Python using the update() method and dictionary unpacking.
