Question
* Make a program faces.py that asks the user to click the mouse, and then draws a face at the point where the user clicked.
* Make a program faces.py that asks the user to click the mouse, and then draws a face at the point where the user clicked. Copy the makeFacefunction definition from the previous exercise, and use it! Elaborate this with a Simple Repeat Loop, so this is repeated six times: After each of 6 mouse clicks, a face immediately appears at the location of the latest click. Think how you can reuse your code each time through the loop!
