Quite apart from the default argument problem, which Duncan has addressed, you have some problems with style and variable names. In particular: give variables meaningful names ; "L".lower() is not meaningful and also suffers from confusion with the digit 1 in some fonts. There is no necessity for the _ in _curList in the above line. Please consider reading http://www.python.org/dev/peps/pep-0008/ > print _curList # yay for printf debugging > if len( l ) <= chunkSize: > _curList.append( l ) > else: > newChunk = l[:chunkSize] > _curList.append( newChunk ) > _chunkify( l[chunkSize:], chunkSize, _curList ) > return _curList > > _chunkify simply breaks a sequence into a sequence of smaller lists of > size <= chunkSize.
