Generate random array of floats between a range

Question

I haven\'t been able to find a function to generate an array of random floats of a given length between a certain range.

I\'ve looked at Random sampling but no funct

Answer 1

np.random.uniform fits your use case:

sampl = np.random.uniform(low=0.5, high=13.3, size=(50,))

Update Oct 2019:

While the syntax is still supported, it looks like the API changed with NumPy 1.17 to support greater control over the random number generator. Going forward the API has changed and you should look at https://docs.scipy.org/doc/numpy/reference/random/generated/numpy.random.Generator.uniform.html

The enhancement proposal is here: https://numpy.org/neps/nep-0019-rng-policy.html

Answer 2

np.random.random_sample(size) will generate random floats in the half-open interval [0.0, 1.0).
