I'm having problem with  data type in python.
I run system.methodSignature('SearchInfo'), it returns [['array', 'struct']].
What should I put as the argument in SearchInfo()? 
And what is struct data type in xml-rpc?
Please help.
Found out the way for <struct> data type for xmlrpc.
 data type is like a dict type. 
For my case, it's actually SearchInfo({'id' : 12345}). 
Good luck to whoever needing this information (:
