NumPy's random_sample() returns a random Float value between 0 (inclusive) and 1 (exclusive).

This method is equivalent to NumPy's random() and ranf().

Parameters

1. size | int or sequence of int | optional

The desired number of random values to generate. By default, size=None, that is, a single random value is returned.

Return value

A NumPy array of random floats between 0 (inclusive) and 1 (exclusive). If size is not specified, a scalar is returned.

Examples

Generate 1D array of random numbers

To generate three random numbers:

np.random.random_sample(3)
array([0.7008265 , 0.61123913, 0.06112331])

Generate 2D array of random numbers

To generate a 2 by 3 two-dimensional array of random numbers:

np.random.random_sample([2,3])
array([[0.59041415, 0.19836836, 0.98704182],
[0.41153823, 0.08973394, 0.72238062]])
