Python Lecture 9 | Dictionaries in Python | Key-Value Pairs, Methods & Practical Coding
🐍 Welcome to Lecture 9 of our Complete Python Programming Course!
In this lecture, we’ll learn Dictionaries in Python, one of the most useful data structures for storing and organizing information using key-value pairs.
📚 Topics Covered:
🔹 What is a Dictionary?
🔹 Key-Value Pairs
🔹 Creating Dictionaries
🔹 Accessing & Retrieving Values
🔹 Using .get() for Safe Access
🔹 Adding New Items
🔹 Updating Existing Values
🔹 Removing Items with pop(), del & clear()
🔹 keys(), values() & items()
🔹 Traversing Dictionaries with Loops
🔹 Dictionary Rules & Common Mistakes
🔹 Practical Coding in VS Code
💻 VS Code Practical:
We create a Student Record System, add an email address, update marks, and use items() to display the complete student details.
🎯 By the end of this lecture, you’ll be able to use dictionaries to store structured data, modify records, safely access values, and loop through key-value pairs.
