Python Coding challenge - Day 43 | What is the output of the following Python code?

 


Solutions - 

You define a variable a and set it to the value 10.

a = 10

You have a while loop. The condition for this loop is a > 8, which means the loop will continue executing as long as a is greater than 8.

In the first iteration of the loop, a is indeed greater than 8 (it's 10), so the loop's code block will be executed.

Inside the loop, you print the current value of a using the print function. The end=' ' argument ensures that the values are printed with a space between them.

print(a, end=' ')

After printing the value of a, you decrement a by 1 using the expression a = a - 1. This reduces the value of a by 1 in each iteration, effectively counting down.

a = a - 1

The loop then returns to the condition a > 8. If the condition is still true (which it is as long as a is greater than 8), the loop continues to the next iteration. Steps 3 to 5 are repeated.

This process repeats until a is no longer greater than 8. When a becomes 8, the condition a > 8 is no longer true, and the loop terminates.

The output of this code will be the numbers from 10 down to 9, each separated by a space:

10 9

Once a reaches 8, the loop stops, and the program continues with any code that follows this loop.
