In the test.py file found in the examples of Skywriter HAT , how would one append the values of x,y, and z to a list? I want to be able to detect left-right motion. It is not as easy as emptyList = emptyList.append(x).
This is the code I am referring to
@skywriter.move()
def move(x, y, z):
print( x, y, z )
