 From the language ref at http://docs.python.org/ref/types.html#l2h-37

  Booleans
  These represent the truth values False and True. The two objects
  representing the values False and True are the only Boolean objects.
  The Boolean type is a subtype of plain integers, and Boolean values
  behave like the values 0 and 1, respectively, in almost all contexts,
  the exception being that when converted to a string, the strings
  "False" or "True" are returned, respectively.

So yes, it's fully guaranteed.
