They don't give you "search in a list of directories" intrinsically, but 
that's simple loop, bailing out on a match, no?

pathlib's glob method is more like glob.glob than os.walk - though 
there's also a walk method in pathlib that's in the same spirit as 
os.walk. The globs are only recursive if you ask them to be, and if you 
don't want wildcarding, don't include any wildcard characters in the 
pattern.
