title: Ways to increment hex in python?
body: <p>I cannot come up with a way to increment a hex value. Let's say I have a variable 
  x = b'\x00' and I just want to keep incrementing it forever in that format how would I do it? x=b'\x00' ...x='\xff'...x='\xff\xff' . Again I want to keep it as a string variable, doesn't have to be hex format but I just want to start at 0 bits and increment to whatever bits.</p>
