Python Program to Find the Sum of Natural Numbers

Natural numbers are a set of positive integers that are used to count and measure quantities.

Python Code : #

The below Python program finds the sum of natural numbers up to a given number:

# Function to find sum of natural numbers up to n
def sum_of_natural_numbers(n):
    # Initialize sum to 0
    sum = 0
    # Iterate over natural numbers up to n
    for i in range(1, n+1):
        # Add current number to sum
        sum += i
    # Return sum
    return sum

# Example usage
n = 10
sum = sum_of_natural_numbers(n)
print("The sum of natural numbers up to", n, "is", sum)

In the above code, the sum_of_natural_numbers function takes a single argument n, which specifies the upper limit of the natural numbers to be summed. It initializes a variable sum to 0, and then iterates over the natural numbers from 1 to n using a for loop. For each number, it adds the current number to sum.

After iterating over all numbers, the function returns the final value of sum.

Finally, we use the sum_of_natural_numbers function to find the sum of natural numbers up to a given number (in this case, 10) and print the result to the console.

For example :

The sum of natural numbers up to 10 is 55
