STINNER Victor <[EMAIL PROTECTED]> added the comment:
Hum, there is not fixer for 2to3. But I might be hard to write such
fixer because walk() generates (dirpath, dirnames, filenames) instead
of (dirpath, filenames).
Python2 prototype:
os.path.walk(path, visit, arg) -> None
with visit: callback(arg, dirpath, filenames)
Python3 prototype:
os.walk(top[, topdown=True[, onerror=None[, followlinks=False]]]) ->
generator
with onerror: callback()
the generator produces (dirpath, dirnames, filenames)
Example:
os.path.walk('Lib/xml/', callback, 42)
can be replaced by
for dirpath, dirnames, filenames in os.walk('Lib/xml/'):
callback(42, dirpath, dirnames + filenames)
About the keyword only: +1 (or +2 :-)).
