title: Convert decimal int to little endian string ('\x##\x##...')
body: <p>I want to convert an integer value to a string of hex values, in little endian.  For example, <code>5707435436569584000</code> would become <code>'\x4a\xe2\x34\x4f\x4a\xe2\x34\x4f'</code>.</p>
  
  <p>All my googlefu is finding for me is <code>hex(..)</code> which gives me <code>'0x4f34e24a4f34e180'</code> which is not what I want.  </p>
  
  <p>I could probably manually split up that string and build the one I want but I'm hoping somone can point me to a better option.</p>
