title: Get a unique computer ID in Python on windows and linux
body: <p>I'd like to get an id unique to a computer with Python on Windows and Linux. It could be the CPU ID, the motherboard serial, ... or anything else.</p>
  
  <p>I looked at several modules (pycpuid, psi, ...) without luck.</p>
  
  <p>Any idea on how to do that?</p>
