    This is as simple as I could make it:

    N=int(input())
countries=set([input() for _ in range(N)])
print(len(countries))

    For Python3

    N = int(input())
stamps = set()
for i in range(N):
    stamps.add(input())

print(len(stamps))

    import sys

    num_stamps = int(sys.stdin.readline()) stamps = {sys.stdin.readline().rstrip() for _ in range(num_stamps)} sys.stdout.write(str(len(stamps)))
