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 ).
This is a convenience function for users porting code from Matlab, and wraps random_sample. That function takes a tuple to specify the size of the output, which is consistent with other NumPy functions like numpy.zeros and numpy.ones.
numpy.random.Generator.integers# method. random.Generator. integers (low, high = None, size = None, dtype = np.int64, endpoint = False) # Return random integers from low (inclusive) to high (exclusive), or if endpoint=True, low (inclusive) to high (inclusive). Replaces RandomState.randint (with endpoint=False) and RandomState.random_integers ...
Random sampling (numpy.random)# Quick start # The 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.
>>> import numpy as np >>> rng = np. random. default_rng (12345) >>> print (rng) Generator(PCG64) >>> rfloat = rng. random >>> rfloat 0.22733602246716966 >>> type (rfloat) <class 'float'> Here we use default_rng to generate 3 random integers between 0 (inclusive) and 10 (exclusive):
Random values in a given shape. randn (d0, d1, …, dn) Return a sample (or samples) from the “standard normal” distribution. randint (low[, high, size, dtype]) Return random integers from low (inclusive) to high (exclusive). random_integers (low[, high, size]) Random integers of type np.int between low and high, inclusive. random_sample ...
For example, it describes the commonly occurring distribution of samples influenced by a large number of tiny, random disturbances, each with its own unique distribution . Note New code should use the normal method of a Generator instance instead; please see the Quick start .
numpy.random.randint¶ 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 high is None (the default), then results are from [0, low).
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.
Return random integers of type numpy.int_ from the “discrete uniform” distribution in the closed interval [low, high]. If high is None (the default), then results are from [1, low ]. The numpy.int_ type translates to the C long integer type and its precision is platform dependent.
