Python Relation.create Examples

Example #1

 def test_create(self):
     self.failUnless(R == Rc)
     I = Relation(Header(a=int, b=int, c=int), Tuple(a=2, b=2, c=0))
     Ic = Relation.create(('a', 'b', 'c'), (int, int, int), [(2, 2, 0)])
     DEE = Relation(Header(), Tuple())
     DEEc = Relation.create((), (), [()])
     self.failUnless(DEE == DEEc)
     DUM = Relation(Header())
     DUMc = Relation.create((), (), [])
     self.failUnless(DUM == DUMc)
     self.failUnless(I == Ic)
     self.failUnless(Relation.create(R.names, R.types, R.rows) == R)
     # crazy:

     rows = list(Tuple(**dict(zip(R.names, t))) for t in R.rows)
