Random module - Githubissues

Need to implement random module in the project. Currently, it implemented in Python. Need to implement it in Cython and cover following functionality https://docs.scipy.org/doc/numpy-1.13.0/reference/routines.random.html

Simple random data

[x] rand(d0, d1, ..., dn) Random values in a given shape.
[x] randn(d0, d1, ..., dn) Return a sample (or samples) from the “standard normal” distribution.
[x] randint(low[, high, size, dtype]) Return random integers from low (inclusive) to high (exclusive).
[x] random_integers(low[, high, size]) Random integers of type np.int between low and high, inclusive.
[x] random_sample([size]) Return random floats in the half-open interval [0.0, 1.0).
[x] random([size]) Return random floats in the half-open interval [0.0, 1.0).
[x] ranf([size]) Return random floats in the half-open interval [0.0, 1.0).
[x] sample([size]) Return random floats in the half-open interval [0.0, 1.0).
[x] choice(a[, size, replace, p]) Generates a random sample from a given 1-D array
[x] bytes(length) Return random bytes.

Permutations

[x] shuffle(x) Modify a sequence in-place by shuffling its contents.
