Examples

>>> from larray import ndtest
>>> axes = ndtest((2, 2)).axes
>>> axes
AxisCollection([
    Axis(['a0', 'a1'], 'a'),
    Axis(['b0', 'b1'], 'b')
])
>>> axes.iter_labels()[0]
(a.i[0], b.i[0])
>>> for index in axes.iter_labels():
...     print(index)
(a.i[0], b.i[0])
(a.i[0], b.i[1])
(a.i[1], b.i[0])
(a.i[1], b.i[1])
>>> axes.iter_labels(ascending=False)[0]
(a.i[1], b.i[1])
>>> for index in axes.iter_labels(ascending=False):
...     print(index)
(a.i[1], b.i[1])
(a.i[1], b.i[0])
(a.i[0], b.i[1])
(a.i[0], b.i[0])
>>> axes.iter_labels(('b', 'a'))[0]
(b.i[0], a.i[0])
>>> for index in axes.iter_labels(('b', 'a')):
...     print(index)
(b.i[0], a.i[0])
(b.i[0], a.i[1])
(b.i[1], a.i[0])
(b.i[1], a.i[1])
>>> axes.iter_labels('b')[0]
(b.i[0],)
>>> for index in axes.iter_labels('b'):
...     print(index)
