From the docs for the Python random module:
Functions for integers:
random.randrange(stop)
random.randrange(start, stop[, step])
Return a randomly selected element from range(start, stop, step).
This is equivalent to choice(range(start, stop, step)), but doesn’t
actually build a range object.
That explains why it only gives you 0, doesn't it. range(0,1) is [0]. It is choosing from a list consisting of only that value.
Also from those docs:
random.random()
Return the next random floating point number in the range [0.0, 1.0).
But if your inclusion of the numpy tag is intentional, you can generate many random floats in that range with one call using a np.random function.
