Je to standardni chovani, struct.pack dela defaultne alignment:

The optional first format char indicates byte order, size and alignment:
  @: native order, size & alignment (default)
  =: native order, std. size & alignment
  <: little-endian, std. size & alignment
  >: big-endian, std. size & alignment
  !: same as >

Davej jednoduse vsude na zacatek fmt vykricnik a vse bude
v network endianu a bez alignmentu.

 >>> struct.pack ('HI', 8, 1)
'\x08\x00\x00\x00\x01\x00\x00\x00'
 >>> struct.pack ('!HI', 8, 1)
'\x00\x08\x00\x00\x00\x01'
