p02421 Card Game
Taro and Hanako are playing card games. They have n cards each, and they compete n turns. At each turn Taro and Hanako respectively puts out a card. The name of the animal consisting of alphabetical letters is written on each card, and the bigger one in lexicographical order becomes the winner of that turn. The winner obtains 3 points. In the case of a draw, they obtain 1 point each.

Write a program which reads a sequence of cards Taro and Hanako have and reports the final scores of the game.

t = 0
h = 0

for _ in range(n):
    tc, hc = input().split()

    if tc > hc:
        t += 3
    elif tc < hc:
        h += 3
    else:
        t += 1
        h += 1
