Python 3.0 has such a formatting operation, but Python 2.x does not.  
However it's not hard to write.

If you really only going to need 8 bits, you can just build a table of 
bit patterns for each integer.  Try this bit of slight cleverness:

 >>> b = ['']
 >>> for k in range(8):
...          b = [i+j for i in ['0','1'] for j in b]
...
 >>> len(b)
256
 >>> b[63]
'00111111'
