Say I have:

class MyClass(db.Model):
  foo1 = db.IntegerProperty()
  foo2 = db.IntegerProperty()
  foo3 = db.IntegerProperty()

obj = MyClass(foo1=100, foo2=200, foo3=300)

I want to loop over foo values.  I found that I can do:

for x in [1, 2, 3]:
  print obj.__dict__['_foo%d' % x]

Is this bad / subject to break?
Is there a better way to do this?
