## Incorrect way to create two circles. 
leftEye = Circle (Point (80 , 50) , 5) 
leftEye.setFill('yellow')
leftEye.setOutline('red')
rightEye = leftEye          # OOPS
rightEye.move (20, 0)

## works but has a "code smell" (google it) : "duplicated code"
leftEye = Circle (Point (80 , 50) , 5) 
leftEye.setFill('yellow')
leftEye.setOutline('red')

rightEye = Circle (Point (100 , 50) , 5) 
rightEye.setFill('yellow')
rightEye.setOutline('red')

# A better way.
leftEye = Circle (Point (80 , 50) , 5) 
leftEye.setFill('yellow')
leftEye.setOutline('red')

rightEye = leftEye.clone()  # make a copy with same position, color, etc.
rightEye.move(20, 0)
