1 2 3 4 5 6 7 8 9 10 |
DesiredNumber = int(input("Enter a DesiredNumberber: ")) if DesiredNumber < 0: print(
"Please Enter a positive DesiredNumberber") else: sum = 0 # while loop to iterate again and again till zero while(DesiredNumber > 0): sum += DesiredNumber DesiredNumber -= 1 print("The sum is",sum) |
Output
Enter a DesiredNumberber: 8
The sum is 36
