Now, we will see a Python program that calculates the sum of the first 'n' natural number. Wolfsshield. Initialize the required variables. In this article, you will learn how to find the sum of digits of a number in python using for loop. Here's an example of the for loop to obtain sum when using Python. javascript text input value . sum = sum+i n number of times with value of i from 1 to n. The range () method used here, returns a sequence of values starting from a value 1 (provided as its first argument) to (n+1)-1 or n (provided as its second argument). C Program to Calculate the Sum of Natural Numbers. Using v-model directive; How to pass an input value . Flowchart of an algorithm (Euclid's algorithm) for calculating the greatest common divisor (g.c.d.) num = int (input ("Please Enter any Num: ")) total = 0 value = 1 while (value <= num): total = total + value value = value + 1 print ("The Sum from 1 to {0} = {1}".format (num, total)) The first step is to declare a new variable and initialize it to 0. After that, we will use the range() function to create a sequence of numbers from 0 to (length of the .

So the return value gets initialized to sum, and its value gets printed.
