Find Sum of Natural Numbers

Python Code:

def sum_of_natural_numbers(limit):
    return (limit * (limit + 1)) // 2

# Taking input for the limit and calculating the sum of natural numbers
def calculate_and_display_sum():
    limit = int(input("Enter the limit: "))
    sum_natural_numbers = sum_of_natural_numbers(limit)
    print("Sum of natural numbers up to", limit, "is:", sum_natural_numbers)
