Question

## velocity
    def get_velocity(self):
        return ( (self.dx, self.dy) )
    def set_velocity (self, new_velocity): 
        self.dx, self.dy = new_velocity
    velocity = property(get_velocity, set_velocity)

The above is from the source code of a module I am using.

So to get the velocity values individually (dx separately, and dy separately), would this work?

self.get_velocity() = lala
lala[1] = dx value and lala[2] = dy value

Is this correct?

Answer 1

No, because when you want to assign the return value of a function to a variable, you have to have the variable on the left and the function on the right:

lala = self.get_velocity()

With that one change, it should work. But note that you can do the same thing with less typing like so:

dx, dy = self.get_velocity()
