Exercise 1.13 - using classes with PsychoPy

Make a “PianoKey” class which contains:

• A visual.Rect object to represent the key on screen
• A event.Mouse object to listen to clicks
• A sound.Sound object to play a sound when pressed

Then add an update method to be called each frame, which:

• Checks for clicks
• Plays the sound if clicked
• Stops the sound when click is released
• Draws the rectangle

If successful, you should be able to copy and paste your class definition above this code and run it:

Things to keep in mind:

• What needs to be imported for this to work?
• What input will the class need in its __init__ function?
• How will it use these inputs?
