Newbie question on dictionary!!!

[Balaji]

Hello everybody...

I want to ask a simple question.

Suppose I have an list say g=['a','b','c','d']

and I have an dictionary say k={'b':20,'a':10}

Now I want to sort this dictionary on the basis of the list and if it
doesnt find any of the element in the list then I wud like to replace
it with zero..

so I would like to modify k into {'a':10,'b':20,'c':0,'d':0}

I have tried all the built in associated with dict and lists but was
not able to come up with an solution...

Can anyone help...
