Hmm, wouldn't it be better to just test for the needed file methods and i=
they aren't there assume it is a file name?
if hasattr(filename, 'write'):
myfile =3D 0
f =3D filename # A file-like ob
myfile =3D 1
f =3D open(str(filename), 'wb')
another pattern I have used for getting around supporting non-unicode pyt=
is something like:
from types import StringType, UnicodeType
StringTypes =3D (StringType, UnicodeType)
from types import StringType
StringTypes =3D (StringType,)
if type(s) in StringTypes:
