🐍 In this video, we tackle a practical **Python exercise**: how to loop through a list of dictionaries and check if a certain key exists. If it does, we print its value — using two different approaches so you can choose the most Pythonic way.
This hands-on example is perfect for beginners looking to master dictionaries and loops, two core concepts you’ll use often in Python. We also discuss the difference between using the `get` method and traditional exception handling to avoid key errors.
📌 *What you’ll learn:*
How to iterate over dictionaries in a list
Checking for key existence safely
Why `dict.get()` is preferred
How this applies to real-world coding and interviews
