Lesson Plan: IT-323 Python Programming 3(2-1)

Week #: Control Flow Statements

Lecture #: While Loops in Python

Learning Objectives:

By the end of this lecture, students will be able to:
✅ Understand the syntax and working of the while loop in Python.
✅ Implement while loops to perform repetitive tasks based on a condition.
✅ Use while loops to solve real-world problems such as printing sequences, summing numbers, and generating multiplication tables. ✅ Apply while loops with conditional statements to control program flow.

Topics Covered:

1. Introduction to While Loops
   • Definition and syntax of the while loop.
   • How a while loop executes based on a condition.
2. Basic Examples
   • Printing numbers from 1 to 10 using a while loop.
   • Printing “Hello, world!” multiple times.
3. Using While Loops in Mathematical Computations
   • Generating multiplication tables.
   • Summing integers from 1 to 100.
   • Calculating the sum of even numbers in a range.
   • Computing squares of numbers.
4. Hands-on Activity: Basic While Loop Practice
   • Modify the given example to print numbers from 1 to 20 instead of 1 to 10.
   • Change the “Hello, world!” loop to print a user-defined number of times.
   • Modify the sum-from-1-to-100 program to sum only odd numbers from 1 to 100.
