Here's how I've learned it so far:
First, there's a convention for 'passing lists as
arguments', which is simply to use 'kw' (I prefer that
one) or 'kwargs' with a '*' in front of them.
But first you need to initialize your data structure
properly, thus:
kw = {} # a empty dictionnary
Then you may want to add stuff inside that kw object:
kw['foo'] = "bar"
Now consider the following data structure:
class Foo:
def __init__(self, **kw):
# do something with kw objects here.
pass
Then here's how to pass the whole kw object as a
argument list:
Foo(**kw)
