In this video, I break down dictionaries from the ground up, covering all the essential concepts you need to start working with this powerful data structure. We explore multiple ways to create dictionaries, how to use for loops to iterate through keys and values, and techniques for adding and deleting items efficiently. Throughout the tutorial, you'll see practical examples of commonly used dictionary methods including get, update, pop, keys, values, and items. I also cover important concepts like memory management with the copy method, setting default values, and creating dictionaries from keys. Whether you're just starting your Python journey or need a refresher on dictionaries, this video gives you hands-on examples you can follow along with in any code editor. The only prerequisites are a basic understanding of for loops and what lists are in Python. By the end of this video, you'll be confident working with dictionaries and ready to implement them in your own projects. All code examples are demonstrated in Google Colab, but you can use any Python environment you prefer.
