如何用PYTHON制作剪刀石头布游戏

打开PYTHON，新建一个空白的PYTHON文档。

player1 = input('Please select your way to win: ')player2 = input('Please select your way to win: ')if player1 == 'rock' and player2 == 'scissors':    print('The winner is player1')elif player1 == 'scissors' and player2 == 'paper':    print('The winner is player1')elif player1 == 'paper' and player2 == 'rock':    print('The winner is player1')我们可以让用户输入选择，然后每个条件这样去判断，但是这样很容易遗漏条件，而且会很复杂。

player1 = input('Please select your way to win: ')player2 = input('Please select your way to win: ')if player1 == 'rock' and player2 == 'scissors':    print('The winner is player1')elif player1 == 'scissors' and player2 == 'paper':    print('The winner is player1')elif player1 == 'paper' and player2 == 'rock':    print('The winner is player1')换了另一个输入就可以看出有问题了。

rules = {'rock': {'scissors': 'wins',                  'paper': 'loses'},        'scissors': {'rock': 'loses',                      'paper': 'wins'},         'paper': {'rock': 'wins',                  'scissors': 'loses'}}player1 = input('Please select your way to win: ')player2 = input('Please select your way to win: ')print('The player1 ' + rules[player1][player2])我们也可以用字典来定义规则，字典里面还可以添加字典，这样直接导出结果。

rules = {'rock': {'scissors': 'wins',                  'paper': 'loses'},        'scissors': {'rock': 'loses',                      'paper': 'wins'},         'paper': {'rock': 'wins',                  'scissors': 'loses'}}player1 = input('Please select your way to win: ')player2 = input('Please select your way to win: ')def who_wins(a, b):    if a == b:        print('Draw')    for i in rules:        if a == i and b == rules[i]:            print('The player1 ' + rules[player1][player2])who_wins(player1, player2)不要忘了我们还可以用FUNCTION来代替繁杂的IF语句。

import randomplayer1 = input('Please select your way to win: ')def who_wins(choice):    options = ['rock', 'scissors', 'paper']    player2 = random.choice(options)    print('player2 is using {}.'.format(player2))        if player1 == 'rock':        if player2 == 'scissors':            print('The winner is player1')        else:            print('The winner is player2')        elif player1 == 'scissors':        if player2 == 'rock':            print('The winner is player2')        else:            print('The winner is player1')            elif player1 == 'paper':        if player2 == 'rock':            print('The winner is player1')        else:            print('The winner is player2')        elif player1 == player2:        return('Draw')            who_wins(player1)我们还可以用RANDOM来随机玩家输入的选项，这样会更加有趣。
