The output from os.walk is a generator, which is an iterator. os.walk
actually calls itself

You could implement that ability in your own objects, but it's not
part of the protocol.
I forgot to mention generator

In general, no.
The usual way to reset an iterator is to re-create it.
walker = os.walk(/home/steve/start)
# ... process files in walker
walker =
