Here in this article, we have provided a python program that can find the sum of n natural numbers using Python loop.

**Prerequisite topics to create this Program**

- Python Input, Output
- Python if…else statement
- Python Data types
- Python Operators
- Python Loop

**Steps**

- First, we ask the user to enter a number n.
- Using the int() function we will convert the entered string into an integer value.
- Now using the for loop we will go through the range 1 to the number n+1, add all the numbers and print sum as an output.

**Python Program to Find the Sum of Natural Numbers:**

**Code:**

n = int(input("Enter the number:" )) sum=0 if n > 1: for i in range(1,n+1): sum+=i print("The sum of all natural number upto",n,"is ",sum) else: print("Please Enter a value greater than 1")

**Output 1:**

Enter the number:2 The sum of all natural numbers upto 2 is 3

**Output2:**

Enter the number:20 The sum of all natural numbers upto 20 is 210
