Fix unit test for segment.__contains__ in Python 3
Paraphrasing the documentation for glue.segment.__contains__
in glue/segments.py
: if a
is a segment
or a sequence of length two,
then a in b
tests if b[0] <= a[0] <= a[1] <= b[1]
. Otherwise,
a in b
tests if b[0] <= a <= b[1]
. The following four tests
happen to work and return False in Python 2, but they raise
a TypeError in Python 3 because Python does not permit comparisons
of numbers with sequences (the exception message is
'<' not supported between instances of 'list' and 'int'
).
self.assertEqual(False, [] in segments.segment(0, 4))
self.assertEqual(False, [0] in segments.segment(0, 4))
self.assertEqual(False, [2] in segments.segment(0, 4))
self.assertEqual(False, [1, 2, 3] in segments.segment(0, 4))
