AI-Guided Tutorial: Conditional Statements and Branching

Learn how to make decisions in your Python programs using if-statements and conditional logic through interactive AI guidance.

Learning Objectives

By the end of this tutorial, you should understand:

• How to use if, elif, and else statements
• Boolean expressions and logical operators
• Nested conditional statements
• Best practices for writing clean conditional code
• Common patterns in decision-making logic

Tutorial Instructions

Part 1: Introduction to Conditional Statements

1. Open VS Code and create conditional_statements_tutorial.py
2. Ask Copilot Chat:

   What are conditional statements in Python and why are they important? Show me basic if, elif, and else statement examples.
   

Part 2: Boolean Expressions and Comparisons

Ask Copilot Chat:

How do boolean expressions work in Python? Show me comparison operators (==, !=, <, >, <=, >=) and logical operators (and, or, not) with practical examples.

Practice Task: Create conditional statements that check user age, grades, or weather conditions.

Part 3: Multiple Conditions with elif

Ask Copilot Chat:

When and how should I use elif statements? Show me examples of multiple condition checking, like grade classification or menu selection.

Practice Task: Create a grade calculator that assigns letter grades based on numeric scores.

Part 4: Nested Conditional Statements

Ask Copilot Chat:

How do nested if statements work? Show me when to use them and how to keep them readable. Include examples of complex decision trees.

Practice Task: Create a program that determines shipping costs based on weight and destination.

Part 5: Conditional Statements with Data Structures

Ask Copilot Chat:

How do I use conditional statements with lists, strings, and dictionaries? Show me checking for membership, empty containers, and data validation.

Practice Task: Validate user input for a registration form.

Part 6: Advanced Conditional Patterns

Ask Copilot Chat:

What are some advanced conditional patterns in Python? Show me ternary operators, short-circuit evaluation, and guard clauses.

Assessment Challenge

Create a Python program that:

• Implements a simple text-based game or quiz
• Uses if, elif, and else statements
• Demonstrates nested conditionals
• Validates user input
• Shows different conditional patterns

Reflection Questions

Ask Copilot Chat:

1. “What are common mistakes when writing conditional statements?”
2. “How can I make my conditional code more readable?”
3. “When should I use nested vs sequential conditionals?”

Take a look at the if-statements lab and make sure you are prepared to work on this in class.
