flatiter
[source]¶ Flat iterator object to iterate over arrays.
A
flatiter
iterator is returned byx.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 row-major, C-style order (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 theflatiter
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])
Attributes
coords
An N-dimensional tuple of current coordinates. Methods
copy
()Get a copy of the iterator as a 1-D array.
