Can string be callable as a method ?

[Jia Lu]

Hi all
 I tried to scan a directory and __import__ all modules ,
<log>
imported module: help
imported module: __init__
imported module: hi
imported module: thanks

and I scaned all methods in them, and put them to a list like:

[['f_chelp', 'f_help'], [], ['f_exclaim', 'f_hi', 'random'],
['f_thanks', 'random']]

But how can I call them from that list??

Thank you.
