Dictionaries in Python Explained | Key-Value Data Structure | Python Bootcamp

In this video, we dive deep into Dictionaries in Python — one of the most important data structures for storing data in key–value pairs.
You’ll learn how to create, modify, and iterate over dictionaries, use nested dictionaries, and master dictionary comprehensions with practical examples.

💡 Topics Covered:
1️⃣ Introduction to Dictionaries
2️⃣ Creating Dictionaries
3️⃣ Accessing Dictionary Elements
4️⃣ Modifying Dictionary Elements
5️⃣ Dictionary Methods (keys(), values(), items())
6️⃣ Copying Dictionaries (Reference, Shallow, Deep)
7️⃣ Iterating Over Dictionaries
8️⃣ Nested Dictionaries
9️⃣ Dictionary Comprehensions
🔟 Real-World Examples:

Count frequency of elements

Merge two dictionaries

🧠 Key Highlights:
✔️ Key–value based data storage
✔️ Keys must be unique and immutable
✔️ Supports powerful methods for manipulation
✔️ Great for organizing structured data
