Why it is showing no output

Question

d=3
While d==15:
Print(d)
d=d+1

Answer 1

The while loop doesn't execute. It will only loop while the condition is true. As d=3 and the loop only executes when d=15, it will be skipped over.

Answer 2

It's because d is never equal 15, therefore the loop never executes. To print the numbers from 3 to 15, you should do it like this:

d = 3
while d <= 15:
print(d)
d += 1

Answer 3
