# Introduction to Adding New Keys to a Dictionary in Python Python's dictionaries are a powerful data structure that allow us to store and access data in an organized way. The keys of a dictionary are used to identify and access its values. It is possible to add new keys to a dictionary, which can be done in multiple ways. In this article, we will look at a few methods that can be used to add new keys to a dictionary in Python. We will also discuss the different ways to access the values of the new keys. Finally, we will discuss a few examples to demonstrate the concepts discussed in this article.

Algorithm: 1. Create a new empty dictionary, or use an existing dictionary. 2. Assign the new key and its corresponding value to the dictionary. 3. Repeat steps 2 and 3 for each new key and its corresponding value that needs to be added to the dictionary. Sample Code: ```python # Create an empty dictionary dict = {} # Add new keys to the dictionary dict['first_key'] = 'first_value' dict['second_key'] = 'second_value' dict['third_key'] = 'third_value' # Print the dictionary print(dict) ``` Output: {'first_key':'first_value', 'second_key':'second_value', 'third_key':'third_value'}
