When you post here, it helps if instead of saying 'it doesnt work' you say 
what you expected to happen and what actually happened (and quote exact 
error messages, dont paraphrase them).

If I try your code it works fine: it defines a function.

If I try to call your function, even though you didn't include a call in 
what 'doesnt work', then I get the exception I would expect, namely that 
you are trying to call args as though it were a function 'args(key)' 
instead of subscripting it as a dictionary 'args[key]'. Fixing that will 
then generate a different error, but I'm sure you'll be able to figure it 
out.
