Part One

原本寫了一堆 if-else，簡化了一下變這樣，可讀性有點低就是了。

shape = {
    'A': 1, 'X': 1, # rock
    'B': 2, 'Y': 2, # paper
    'C': 3, 'Z': 3, # scissors
}
score = 0
with open('02.txt', 'r') as fp:
    for line in fp:
        line = line.strip()
        if len(line):
            oppo, mine = line.split(' ')
            score += shape[mine]
            if shape[oppo] == shape[mine]:
                score += 3
            elif shape[mine]-shape[oppo] in [1, -2]:
                score += 6
print(score)

                score += shape[oppo]
            elif stat == 'X':
                score += 3 - (4-shape[oppo])%3
            elif stat == 'Z':
                score += shape[oppo]%3 + 1
print(score)
