Python While Loop Exercise Questions
Below are two exercise questions on Python while loop. We have covered 2 important exercise questions based on the bouncing ball program and the countdown program.
Q1. While loop exercise question based on bouncing ball problem
Python
initial_height = 10 bounce_factor = 0.5 height = initial_height while height > 0.1: print("The ball is at a height of", height, "meters.") height *= bounce_factor print("The ball has stopped bouncing.") |
Output
The ball is at a height of 10 meters.
The ball is at a height of 5.0 meters.
The ball is at a height of 2.5 meters.
The ball is at a height of 1.25 meters.
The ball is at a height of 0.625 meters.
The ball is at a height of 0.3125 meters.
The ball is at a height of 0.15625 meters.
The ball has stopped bouncing.
Q2. Simple while-loop exercise code to build countdown clock
Python
countdown = 10while countdown > 0: print(countdown) countdown -= 1print("Blast off!") |
Output

Python While Loop
Python While Loop is used to execute a block of statements repeatedly until a given condition is satisfied. When the condition becomes false, the line immediately after the loop in the program is executed.
