Aug 16, 2015 · range(m,n) iterates from m to n-1. If you want sum of numbers from m to n (including m and n) for i in range(m, n+1): sum+=i

n = input("Enter Number to calculate sum") n = int (n) #average = 0. #sum = 0 sum = 0. for num in range(0,n+1,1): sum = sum+num print("SUM of first ", n, "numbers is: ", sum ) # Print sum of numbers from 1 to N inclusive def sum2N(N): r = 0 for i in range(N+1): #for i in range(0,N+1,1): #r+=i r=r+i return(r) print(sum2N(10))

To write a Python program for finding the sum of ‘n’ numbers, you can follow these steps: Start by taking user input for the total number of elements to be summed. Create a variable to store the sum, initialized to 0. Use a loop to iterate ‘n’ times, prompting the user to enter each number. Read each input number and add it to the sum variable.

Jul 2, 2024 · In this example, a Python function sum_of_natural_numbers is defined to calculate the sum of the first N natural numbers using a while loop. The function initializes variables total and count, iterates through the numbers from 1 to N, and accumulates the sum in …

Jan 13, 2022 · numbers = [1, 2, 3, 4] print(sum(numbers)) Using a for loop you have to save sum in a variable and store result into this. Example: number = int(input("Number: ")) sum = 0 for i in range(1, number + 1): sum += i print(sum)

In this article, we will explore how to write a Python program to calculate the sum of n numbers using a for loop. This program is a fundamental exercise that showcases the use of loops in Python and helps us understand the iterative nature of programming.

In this program, you'll learn to find the sum of n natural numbers using while loop and display it.
