Ini berperilaku persis seperti walk(), kecuali ia menghasilkan 4-tuple (dirpath, dirname, nama file, dirfd), dan mendukung dir_fd.
os.fwalk(top='.', topdown=True, onerror=None, *, follow_symlinks=False, dir_fd=None)import os
for root, dirs, files, rootfd in os.fwalk('python/Lib/email'):
print(root, "consumes", end="")
print(sum([os.stat(name, dir_fd=rootfd).st_size for name in files]),
end="")
print("bytes in", len(files), "non-directory files")
if 'CVS' in dirs:
dirs.remove('CVS') don't visit CVS directoriesDelete everything reachable from the directory named in "top",
assuming there are no symbolic links.
CAUTION: This is dangerous! For example, if top == '/', it
could delete all your disk files.
import os
for root, dirs, files, rootfd in os.fwalk(top, topdown=False):
for name in files:
os.unlink(name, dir_fd=rootfd)
for name in dirs:
os.rmdir(name, dir_fd=rootfd)
