Err no. The attribute is the _name_ of the function,
not the term of something like calling it.

queryname="sql_getContryGroupings"

myQueryObject = getattr(context,queryname)

myResults = myQueryObject()

Well, I have to say this is somewhat basic understanding
of the language (the attributename, function call is 
similar across most languages)

With python always have an interactive python interpreter
running where you can quickly check your ideas and
get a feeling of the language.
