On one hand, this is the "development of python itself" list; this
issue was more aimed to the general python list, of you was sure that
this is a real bug, to the issue tracker.

On the other hand, this is not a bug! If you pass a parameter to
lstrip it will (quoted from its help) "remove characters in chars
instead.", so the moment you pass "device_", it removes all those
characers from the left... note that the 'i' is removed twice.
