[Solved] Why would the union of an empty set with another set results in an empty set in python? [closed]

Question

No! The result of the union between the set empty and b is always b.

a = set()
b = set([1,2])
print a.union(b) #return {1, 2}

The intersection between an empty set and anything is the set empty.

print a.intersection(b) #return set()
