You can answer that yourself: >>> import struct, wave >>> struct is wave.struct True > Why putting struct in two places ? Assumming your code is part of a module called mymodule.py > import wave > val = wave.struct.pack(...) > import struct > val = struct.pack(...) you can now also do import mymodule val = mymodule.struct.pack(...) or even val = mymodule.wave.struct.pack(...) Do you see the pattern? You should ;) -- https://mail.python.org/mailman/listinfo/python-list
