In this assignment, you will create your own basic Error Detector $($called "error$\_$detector.py$\text{'})$ by checking the Parity of the number input by the user. Let's agree that all input should be even, so that all even input gives the message $"$OK$!"$ and an odd input will print "Error detected!". For bonus points: use a string function to check whether the given input is a digit and exit gracefully if invalid input is given.
