python: os.path pathname split examples

From http://docs.python.org/2/library/os.path.html,

>>> import os
>>> pth="/abeja/blanca/zumbas/ebria/de/miel/en/mi/alma/y.te.tuerces"

>>> os.path.split(pth)
('/abeja/blanca/zumbas/ebria/de/miel/en/mi/alma', 'y.te.tuerces')

>>> os.path.dirname(pth)
'/abeja/blanca/zumbas/ebria/de/miel/en/mi/alma'

>>> os.path.basename(pth)
'y.te.tuerces'

>>> os.path.splitext(os.path.basename(pth))
('y.te', '.tuerces')

>>> os.path.splitext(pth)
('/abeja/blanca/zumbas/ebria/de/miel/en/mi/alma/y.te', '.tuerces')
