Converting values in a dictionary to individual lists

How do i convert the values in a dictionary to individual lists? For example: dictionary = {‘a’:[1,2,3], ‘b’:[4,5,6],’c’:[8,9,10]} outcome: a = [1,2,3] b = [4,5,6] c = [8,9,10] So far i could only think of creating individual lists and putting it into the list. Is there any looping or better ways to do this?
