estimate_gradiente function type annotations no output

[Francisco Giordano Silva]

Hi there,

Not sure if this is an issue but , chapter 8 Gradient descent; estimate_gradient function should it return a Vector type?
def estimate_gradient(f: Callable[[Vector], float], c: Vector, h: float = 0.0001) -> Vector: return [partial_difference_quotient(f, v, i, h) for i in range(len(v))]
either way thanks for the great book :)

you're correct, I guess I just missed annotating that return type (the type annotations are optional, so it doesn't hurt anything to not have them, but I meant to put them everywhere)
