Title: Mastering Python Dictionaries: Exploring the setdefault() Method

Description:
Welcome to our Python programming tutorial! In this video, we delve into the powerful `setdefault()` method in Python dictionaries. If you've ever wondered how to efficiently handle default values for keys that may or may not exist in your dictionaries, this tutorial is for you.

The `setdefault()` method is a handy tool that allows you to set default values for keys in dictionaries. If a key is present in the dictionary, it returns the corresponding value. If the key is not found, `setdefault()` inserts the key with the specified default value and then returns that value.

In this video, we'll walk you through the syntax of `setdefault()` and demonstrate its usage with practical examples. You'll learn how to:

1. Use `setdefault()` to retrieve existing values for keys.
2. Insert new keys with default values using `setdefault()`.
3. Understand the importance of default values in dictionary operations.

By mastering the `setdefault()` method, you'll enhance your Python programming skills and gain a deeper understanding of dictionary manipulation. Don't miss out on this essential Python feature—watch the video now and level up your coding expertise!
