Quindi davvero secondo te conviene partire da Python e non da C# se una persona si pone l'obiettivo di scrivere programmi che interagiscono a basso livello con l'hardware ? Secondo me è un'assurdità.
Nota bene che io non dico che sia un'assurdità imparare a programmare con Python, tutt'altro, dico che è assurdo in questo caso.

  return ''.join(chr((Value >> Shift) & 255) for Shift in (0, 8, 16, 24))

  return tuple((Value >> Shift) & 15 for Shift in(0, 4, 8, 12, 16, 20, 24, 28))

  List = []
  for Name in Names:
    if Name and (Value & 1):
      List.append(Name)
    Value >>= 1
  return List

def CPUID(Function):
  eax = c_int(); ebx = c_int(); ecx = c_int(); edx = c_int()
  hw.Cpuid(Function, byref(eax), byref(ebx), byref(ecx), byref(edx))
  return eax.value, ebx.value, ecx.value, edx.value

E' abbastanza assurdo per te?

P.S. Il programma ha bisogno che i file WinRing0.dll e WinRing0.sys della cartella "release" del progetto http://openlibsys.org/ siano presenti nella cartella da cui verrà lanciato (oppure che si trovino nel path).
