title: Python: moving to a new computer
body: <p>I'm moving from a computer with  windows xp  to one with windows 7 (64 bit) and I want to install Python on the new machine.  I'm currently using python 2.7 and 3.2 and a bunch of packages</p>
  
  <p>1) Should I install the 64 bit versions?</p>
  
  <p>2) How can I tell which packages I currently have, so that I can get those for the new machine?</p>
  
  <p>If these are duplicates (my search skills seem to be failing), please point me to the threads where they're discussed.</p>
