Python: See if one set contains another entirely?

Question

Is there a fast way to check if one set entirely contains another?

Something like:

>>>[1, 2, 3].containsAll([2, 1])
True

>>>[1, 2,         


        

Answer 1

>>> set([1,2,3]).issuperset(set([2,1]))
True 
>>>    
>>> set([1,2,3]).issuperset(set([3,5,9]))
False
