This expects the function g to be called with the parameters "s" and
"kwds"

This expects to be passed the parameter "s", and various keyword
arguments, which will be put into the dict "kwds".

when you call 

o.g("string",**kwds)

you are passing the parameter "string" as the first parameter, and then
a sequence of keyword arguments taken from kwds, which will be passed
separately.

This is what the second form expects, but not what the first one
expects.
