How can I get autocomplete arguments before ENTER?

Question

There is a file argComp.py in Ubuntu 14.04 LTS. I install argcomplete 1.0.0 module successfully.

chmod +x argComp.py

and then

data = [ name1 : { address1 : [Korea, Seoul ] }, name2 : { address2 : [ USA, LA ] } ]

./argComp.py --name [tab]

./argComp.py --name
name1 name2

./argComp.py --name name1 --address [tab]
Korea Seoul

I want read the my argument by realtime before the user presses ENTER. For this, the argcomplete module should read text name in --name name1, and then check data by name1.

I could I get data and make the --address list ?

I want to implement this concept to file browser realtime..

Please help, and thank you in advance.
