A zoo's inventory holds all sorts of things. The starter code has four classes: Animal, Dog (a child of Animal), Puppy (a child of Dog), and Robot (no parent). Don't change them.
Write family_report(things). It returns a dictionary with three counts:
"animals": how many things are an Animal or any child of it,"dogs": how many are a Dog or any child of it,"others": how many are not an Animal at all.The list can contain anything, including text and numbers. An empty list gives all three counts as 0.
