That example was introduced in r16743 as:
>>> spcs = ["  Apple", " Banana ", "Coco  nut  "]
>>> print [s.strip() for s in spcs]
['Apple', 'Banana', 'Coco  nut']

and was changed in r16831 to:
>>> freshfruit = ['  banana', '  loganberry ', 'passion fruit  ']
>>> [weapon.strip() for weapon in freshfruit]
['banana', 'loganberry', 'passion fruit']

I think that the fresh fruits can really be considered as dangerous
weapons - especially the banana. <wink>
