Python Quiz #38: While Loop Quiz | Python for Beginners | Python Tutorial
@yasirbhutta In this video, we dive into a simple yet powerful Python loop example to help you understand the basics of the while loop. We start by setting an initial value and explore how the loop condition works. Watch as we decrement a variable and print its value with each iteration.
What You'll Learn:
How the while loop operates in Python.
Using a decrementing variable inside a loop.
Understanding loop termination conditions.
Explanation:
1. *Initialization:*
`x` is initialized to `10`.
2. *Loop Condition:*
The `while` loop checks if `x` is greater than `0`. If true, the loop will continue running.
3. *Loop Execution:*
In the first iteration, `x` is `10`, so `10` is printed. Then `x` is decreased by `2`, making `x = 8`.
In the second iteration, `x` is `8`, so `8` is printed. Then `x` is decreased by `2`, making `x = 6`.
This continues with `x` taking the values `6`, `4`, and `2`, printing each of these values.
After `x` is `2`, it is decreased by `2` again, making `x = 0`.
4. *Loop Termination:*
When `x` becomes `0`, the condition is no longer true, so the loop stops, and no more values are printed.
Conclusion:
The output of this code will be `10 8 6 4 2`. Therefore, the correct answer is:
*B) 10 8 6 4 2*
