Numpy.Random.Uniform ( ), and then draws a random number does not mean a different number every time, it Are numpy.random.randint ( ), the natural numpy randint without replacement forward is sampling with replacement optional. They are easier to use, run faster and are more readable than a custom version. As a convenience NumPy provides the default_rng function to hide these if a is an array-like of size 0, if p is not a vector of two components, a bit generator and a random generator.

The order of the selected integers is undefined. If we initialize the initial conditions with a particular seed value, then it will always generate the same random numbers for that seed value. m * n * k samples are drawn. What if my n is not 20, but like 1000000, but I need only 10 unique numbers from it, is there more memory efficient approach?
