Python program to print sum of N natural numbers
Sum of N natural numbers using Python :
In this article we will perform addition on first n natural numbers, where n is a number up to which we have to perform addition. So we create a python program to print the sum of n natural numbers.
For better understanding let’s suppose the value of n is 5 then,
Sum of first 5 natural numbers will be (1+2+3+4+5) = 15.
So we create a python program to calculate sum of first n natural numbers.
Step 1 : Ask the user to enter a number which will denote the limit.
Step 2 : Declare a variable to store the addition and initialize it with 0.
Step 3 : Use a loop to perform iterations for adding natural numbers from 1 till the limit entered by the user.
Step 4 : Use a statement for addition purpose.
Step 5 : Print the result.
n=int(input("Enter a number: ")) sum=0 for i in range(n+1): sum=sum+i print("Sum is:",sum)
Enter a number: 2 Sum is: 3
