• 10th Standard
• 11th Standard
• 12th Standard
• CBSE Board Students

Language: English

Topics Covered

✅ What is a Dictionary in Python
✅ Key-Value Pairs Explained
✅ Creating Dictionaries
✅ Adding Values to a Dictionary
✅ Accessing Dictionary Values
✅ Initializing Dictionaries with Values
✅ Iterating Through Dictionaries
✅ Removing Values from Dictionaries
✅ Checking if a Key Exists

What We Practiced

In this session we:

• Created Python dictionaries
• Stored student names and enrollment numbers
• Learned how key-value pairs work
• Printed dictionary values
• Iterated through dictionaries using loops
• Deleted values using del
• Discussed alternative methods like pop
• Checked if keys exist before accessing them
• Learned why fail-safe coding is important

VS Code Tips Covered

We also explored:

• Running Python files in VS Code
• Formatting Python code
• Using the Autopep8 extension
• Keeping code readable and organized

Important Learning

One important takeaway from this video:

👉 Always write fail-safe code.

Before accessing or deleting values from a dictionary, make sure the key exists first.
This helps avoid runtime errors and crashes.

We also learned why proper code formatting matters when working in teams or large projects.
