# Python Program to Find the Sum of Natural Numbers

Here’s an example Python code to find the sum of natural numbers:

```# Get input from user for the last number
n = int(input("Enter a positive integer: "))

# Compute the sum of natural numbers using a loop
sum = 0
for i in range(1, n+1):
sum += i

# Display the result
print(f"The sum of first {n} natural numbers is {sum}")```

In this code, we first prompt the user to enter a positive integer using the `input()` function and convert it to an integer using the `int()` function. We then use a `for` loop to iterate over the range of natural numbers from 1 to the last number entered by the user. Within the loop, we add each natural number to a variable called `sum`. Finally, we use the `print()` function to display the result to the user using f-strings to format the output.

When you run this code, it should prompt you to enter a positive integer. After you enter a number, it should compute the sum of the natural numbers from 1 to the entered number and display the result, similar to the following:

```Enter a positive integer: 10
The sum of first 10 natural numbers is 55```

Note that you can modify the messages or the formatting of the output as needed.
