numpy.random.rand — NumPy v2.1 ManualLearn how to create an array of random values from a uniform distribution over [0, 1) with numpy.random.rand. This is a convenience function for users porting code from Matlab, and wraps random_sample.
random.randint(low, high=None, size=None, dtype=int) #. Return random integers from low (inclusive) to high (exclusive). Return random integers from the “discrete uniform” distribution of the specified dtype in the “half-open” interval [low, high).
If positive int_like arguments are provided, randn generates an array of shape (d0, d1,..., dn), filled with random floats sampled from a univariate “normal” (Gaussian) distribution of mean 0 and variance 1.A single float randomly sampled from the distribution is returned if no argument is provided. Parameters:
numpy.random.uniform# random. uniform (low = 0.0, high = 1.0, size = None) # Draw samples from a uniform distribution. Samples are uniformly distributed over the half-open interval [low, high) (includes low, but excludes high). In other words, any value within the given interval is equally likely to be drawn by uniform.
numpy.random.normal# random. normal (loc = 0.0, scale = 1.0, size = None) # Draw random samples from a normal (Gaussian) distribution. The probability density function of the normal distribution, first derived by De Moivre and 200 years later by both Gauss and Laplace independently , is often called the bell curve because of its characteristic shape (see the example below).

Using the NumPy Random Number Generator - Real PythonYou can use your new skills to generate random numbers both individually and as NumPy arrays. You know how to select random items, rows, and columns from an array and how to randomize them. Finally, you gained insight into how NumPy supports random selection from statistical distributions.
