You can answer that yourself:

>>> import struct, wave
>>> struct is wave.struct
True

Assumming your code is part of a module called mymodule.py

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 ;)
