numpy.random.rand — NumPy v2.1 ManualCreate an array of the given shape and populate it with random samples from a uniform distribution over [0, 1). Parameters: d0, d1, …, dn int, optional. The dimensions of the returned array, must be non-negative. If no argument is given a single Python float is returned. Returns: out ndarray, shape (d0, d1,..., dn) Random values.
Parameters: low int or array-like of ints. Lowest (signed) integers to be drawn from the distribution (unless high=None, in which case this parameter is one above the highest such integer). high int or array-like of ints, optional. If provided, one above the largest (signed) integer to be drawn from the distribution (see above for behavior if high=None).If array-like, must contain integer values
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).

random — Generate pseudo-random numbers — Python 3.12.6 documentationThis module implements pseudo-random number generators for various distributions. For integers, there is uniform selection from a range. For sequences, there is uniform selection of a random element, a function to generate a random permutation of a list in-place, and a function for random sampling without replacement.

Random sampling (numpy.random) — NumPy v2.1 ManualThe numpy.random module implements pseudo-random number generators (PRNGs or RNGs, for short) with the ability to draw samples from a variety of probability distributions. In general, users will create a Generator instance with default_rng and call the various methods on it to obtain samples from different distributions.
