numpy.iterable#

numpy.iterable(y)[source]#

Check whether or not an object can be iterated over.

Parameters:

yobject: Input object.

Returns:

bbool: Return True if the object has an iterator method or is a sequence and False otherwise.

Notes

In most cases, the results of np.iterable(obj) are consistent with isinstance(obj, collections.abc.Iterable). One notable exception is the treatment of 0-dimensional arrays:

>>> from collections.abc import Iterable
>>> a = np.array(1.0)  # 0-dimensional numpy array
>>> isinstance(a, Iterable)
True
>>> np.iterable(a)
False

Examples

>>> np.iterable([1, 2, 3])
True
>>> np.iterable(2)
False
