numpy.flatiter

class numpy.flatiter

Flat iterator object to iterate over arrays.

A flatiter iterator is returned by x.flat for any array x. It allows iterating over the array as if it were a 1-D array, either in a for-loop or by calling its next method.

Iteration is done in C-contiguous style, with the last index varying the fastest. The iterator can also be indexed using basic slicing or advanced indexing.

ndarray.flat

Return a flat iterator over an array.

ndarray.flatten

Returns a flattened copy of an array.

Notes

A flatiter iterator can not be constructed directly from Python code by calling the flatiter constructor.

Examples

>>> x = np.arange(6).reshape(2, 3)
>>> fl = x.flat
>>> type(fl)
<type 'numpy.flatiter'>
>>> for item in fl:
...     print item
...
0
1
2
3
4
5

>>> fl[2:4]
array([2, 3])

Methods
