__getattr__ for static/class variables in python

Question

I have a class like:

class MyClass:
     Foo = 1
     Bar = 2

Whenever MyClass.Foo or MyClass.Bar is invoked, I n

Answer 1

For the first, you'll need to create a metaclass, and define __getattr__() on that.

class MyMetaclass(type):
  def __getattr__(self, name):
    return '%s result' % name

class MyClass(object):
  __metaclass__ = MyMetaclass

print MyClass.Foo

For the second, no. Calling str(MyClass.Foo) invokes MyClass.Foo.__str__(), so you'll need to return an appropriate type for MyClass.Foo.
