Yes.
>>> def test(name, where):
... return "select * from %s" % (name,) + ("" if not where else (" where %s" %
where))
...
>>> test('mine', 'x = 3')
'select * from mine where x = 3'
>>> test('mine', None)
'select * from mine'
>>> test('yours', 'barfle is not NULL')
'select * from yours where barfle is not NULL'
