(This being Py3)

If 0 <= x <= 9, bytes((ord('0')+n,)) will work. Otherwise, no. You would 
have to do the same thing str(int) does, which is to reverse the 
sequence of remainders from dividing by 10 and then add ord('0') to get 
the char code.

Note: an as yet undocumented feature of bytes (at least in Py3) is that
bytes(count) == bytes()*count == b'\x00'*count.
