Learn Python • #7 Dictionaries • The Most Useful Data Structure?

Dictionaries are a data structure that store key-value pairs, and is quite possibly the most useful data structure in Python. Dictionaries allowing for fast and efficient data retrieval. We'll cover how to create and manipulate dictionaries, as well as common methods for iterating through them. You'll also learn how you can use dictionaries to represent real objects (e.g. like a shoe), and how to turn that data into a format that you can send over the internet to other apps (JSON serialization). This video is part of a beginner tutorial series for anyone who wants to learn Python from scratch, and get to a point where you can start coding your own projects. 🔗 Project Code (GitHub): https://github.com/pixegami/python-fo... 🔗 Full Playlist:    • Python For Beginners (Full Course)   🔗 Next Chapter: Coming Tomorrow! 👉 Follow me on Twitter: @pixegami 📚 Chapters 00:00 - Dictionaries vs List 03:42 - How to Use a Dictionary 05:03 - Adding, Updating and Removing items 12:03 - Dictionary Built-In Methods 13:15 - Looping Through a Dictionary 14:58 - Dictionary as Objects 16:45 - JSON Serialization 19:12 - Coding Exercise: Dictionaries
