You can use itertools.groupby to accomplish this. Essentially it will group consecutive runs of True and False respectively, then just keep the groups of True using a list comprehension.

>>> from itertools import groupby
>>> values = [True, False, False, True, True]
>>> [list(g) for k, g in groupby(values) if k]
[[True], [True, True]]
