Can string formatting be used to convert an integer to its binary form ?

I didn't fell over this problem so far but
I *would* have expected to find something
like a 'pack' operator (as in Perl).

And voilá, there is (even basically identical to Perl):

  from struct import *

  a = 199
  a_bin_str = pack('L', a)
