Please help with this complex problem

Compute a small loop python code that accomplish this tasks:

- A continuous loop with a "while True" statement will monitor whenever a switch is press or not

- by updating a boolean function using GPIO pin of a raspberry pi 4

- Add an if statement to check and see if the button has been pressed, validating the boolean function as the argument

- If it is true, then print the value. If it is not true, then do nothing.
