Modifying dirs
in-place will prune the (subsequent) files and directories visited by os.walk
:
# exclude = set(['New folder', 'Windows', 'Desktop'])
for root, dirs, files in os.walk(top, topdown=True):
dirs[:] = [d for d in dirs if d not in exclude]
From help(os.walk):
When topdown is true, the caller can modify the dirnames list in-place
(e.g., via del or slice assignment), and walk will only recurse into
the subdirectories whose names remain in dirnames; this can be used to
prune the search…
