You could first convert your lists into a set. In python, a set is a dictionary that contains only keys and no values. Since keys are unique, duplicate entries are eliminated automatically. Then, convert the set back into a list and print. You can achieve this with a nice one-liner:

print list(set().union(a, b, c))
