numpy.random.standard_normal

numpy.random.standard_normal(size=None)

Returns samples from a Standard Normal distribution (mean=0, stdev=1).

Parameters:

size : int or tuple of ints, optional

Output shape. Default is None, in which case a single value is returned.

Returns:

out : float or ndarray

Drawn samples.

Examples

>>> s = np.random.standard_normal(8000)
>>> s
array([ 0.6888893 ,  0.78096262, -0.89086505, ...,  0.49876311, #random
       -0.38672696, -0.4685006 ])                               #random
>>> s.shape
(8000,)
>>> s = np.random.standard_normal(size=(3, 4, 2))
>>> s.shape
(3, 4, 2)
