Examples

A simple way to check sorting

>>> from is_sorted import is_sorted
>>> is_sorted([1, 2, 3, 4, 5, 6])
True
>>> is_sorted([1, 3, 2, 0])
False
>>> is_sorted([5, 4, 3, 2, 1], reverse=True)
True
>>> is_sorted([(1, 2), (2, 0), (3, 10), (3, 9), (4, 5)], key=lambda x: x[0])
True

Multiple keys sorting

>>> data = [(1, 2), (1, 1), (2, 3), (2, 3), (3, 5)]
>>> is_sorted(data, multi=[(lambda x: x[0], False), (lambda x: x[1], True)])
True
