I=92ve used the comma form with struct.unpack() frequently:

count, =3D struct.unpack(=91!I=92, self.packet)

That=92s after I don=92t use it and end up scratching my head for a =
while and finally remember that unpack returns a tuple regardless of how =
many things I unpack from it. It=92s just natural if you=92re doing lots =
of single unpacks to think it returns a single value. Either way, I much =
prefer it to:

count =3D struct.unpack(=91!I=92, self.packet)[0]=
