numpy.random.mtrand.RandomState.tomaxint

RandomState.tomaxint(size=None)

Random integers between 0 and sys.maxint, inclusive.

Return a sample of uniformly distributed random integers in the interval [0, sys.maxint].

Parameters :

size : tuple of ints, int, optional

Shape of output. If this is, for example, (m,n,k), m*n*k samples are generated. If no shape is specified, a single sample is returned.

Returns :

out : ndarray

Drawn samples, with shape size.

>>> RS = np.random.mtrand.RandomState() # need a RandomState object
