Accessing Dictionary Values

Let's build a dictionary to represent a book in a library:


              12
            
book = {"title": "Pride and Prejudice", "author": "Jane Austen", "year": 1813}
print(book)

This dictionary includes three key-value pairs:

In a dictionary, you can retrieve an item by referencing its key. Here's an example of accessing the publication year of the book:


              1234
            
book = {"title": "Pride and Prejudice", "author": "Jane Austen", "year": 1813}

publication_year = book["year"]
print(publication_year)  # Output: 1813

In the code provided:

Python searches for the key "year" in the book dictionary;
It retrieves the value associated with the key (1813) and assigns it to the variable publication_year.

The value is then printed, demonstrating how keys allow quick and specific access to dictionary values.

Task

Print the title of the book and the year it was published from the book dictionary. Use key indexing to retrieve the information.
