Depends on what you think 'null' should be - either compare
it to the None object, or to the empty string:

if s =3D=3D None or s =3D=3D "":
=09print "This might be considered a null string"

This contrasts with systems like the Oracle database,
where a null value can have a type. A real Python null
is always None.
