Pythonからはじめる数学入門 (Amit Saha (著)、黒川 利明 (翻訳)、オライリージャパン)の5章(集合と確率を操作する)、5.4(プログラミングチャレンジ)、問題5-4(トランプをよく切る)を取り組んでみる。

問題5-4(トランプをよく切る)

コード(Emacs)

#!/usr/bin/env python3
# -*- coding: utf-8 -*-

import random


class Card:

    def __init__(self, suit, rank):
        self.suit = suit
        self.rank = rank

    def __str__(self):
        return '{0} of {1}'.format(self.rank, self.suit)

if __name__ == '__main__':
    cards = [
        Card(suit, rank)
        for suit in ['clubs', 'spades', 'hurts', 'diamonds']
        for rank in (
            ['ace'] + list(range(2, 11)) + ['jack', 'queen', 'king']
        )
    ]
    for _ in range(2):
        random.shuffle(cards)
        print('--------------------------------------------------')
        print('\n'.join(map(str, cards)))
