Yep, it's just another name. "lost" would have worked just as well.
It's pretty typical around here to see "_" used when a tuple is unpacked
but some of the values aren't used. So if you see something like::
for _, dirs, _ in os.walk(top):
...
it just means that the "..." code is only going to use "dirs" (not the
root path or files that are also available from the os.walk() iterator).
