This form is the most suited for what your doing:

> class Foo:
>   var = 'lala'

It is a good practice to place your globals into a class (making them non global by the way). It helps also writing good documentation in docstrings.

I would add:

> class Foo:
>   """Hold the secrets of eternity"""
>   var = 'lala'
>   """One variable"""
>   ANY_CONSTANT = 14
>   """The universal answer to all questions"""

Having strong naming convention also helps a lot.

PS: FYI, in the second form, var is an instance variable, and you need to create an instance to access it => Bar().var while Foo.var is enough for the first form.
