In this Python program, we will learn how to find the sum of the natural numbers. Natural numbers are the positive integers or non-negative integers that start from 1 and end at infinity, such as 1,2,3,4,5,6,7,8,9,10,……,∞.
Here is the code of the program to find the sum of the natural numbers.
# Python Program to Find the Sum of Natural Numbers # Sum of natural numbers up to num # Take the Input From the User num = int(input("Enter the Number: ")) holdNum = num if num < 0: print("Enter a positive number") else: sum = 0 # use while loop to iterate until zero while(num > 0): sum += num num -= 1 print("The Sum of First",holdNum,"Natural Number is: ", sum)
Enter the Number: 10
The Sum of First 10 Natural Number is: 55
