numpy.ndindex

class numpy.ndindex(*shape) [source]

An N-dimensional iterator object to index arrays.

Given the shape of an array, an ndindex instance iterates over the N-dimensional index of the array. At each iteration a tuple of indices is returned, the last dimension is iterated over first.

Parameters:	`*args` : ints The size of each dimension of the array.

(1, 0, 0)
(1, 1, 0)
(2, 0, 0)
(2, 1, 0)

Methods

ndincr()	Increment the multi-dimensional index by one.
next()	Standard iterator method, updates the index and returns the index tuple.
