Write a Python program that calculates the sum of the first N of even numbers, where N is a

positive integer entered by the user. Ensure that only positive $($natural numbers$)$ integer values

are accepted. Use a for loop to iterate from $1$ to N inclusively, and calculate the running total of

even numbers.

After calculating the sum, print the total sum of the first N even numbers.

Submit your Python script $(*.$py$)$ on CodeGrade named: SU$4\_2.$py

Example:

If the user enters N $=4,$ the program should calculate the sum as $2+4+6+8=20,$ and print the

result as $$The sum of the first $4$ even numbers is $20.$ Use f$-$string formatting to print the output.
