You don't need setattr/getattr if you know in advance the name of the 
attribute you need to access and you can get a reference to the object 
whose attribute it is. So:

  >>> import sys
  >>> x = "Hello, Paulo"
  >>> sys.modules['__main__'].x
'Hello, Paulo'
  >>> globals()['x']
'Hello, Paulo'
  >>>
