在python中添加字典的值

Question

我想添加单个玩家的得分，并希望显示该玩家得分最多的得分。这是我所指的字典示例：

{'match1': {'player1': 57, 'player2': 38},
 'match2': {'player3': 9, 'player1': 42},
 'match3': {'player2': 41, 'player4': 63, 'player3': 91}}

我尝试了许多解决方案，但无法制定一个逻辑，以便将不同比赛中各个球员的得分相加。任何帮助都将是可观的。提前致谢。

Answer 1

遍历嵌套的dictionary 并将分数加到玩家总数字典中。

def find_totals(d):
    total = {}
    for match, results in d.items():
        for player, score in results.items():
            total[player] = total.get(player, 0) + score
    return total

样本输出

>>> d = {'match1':{'player1':57, 'player2':38}, 'match2':{'player3':9, 'player1':42}, 'match3':{'player2':41, 'player4':63, 'player3':91}}
>>> print find_totals(d)
{'player2': 79, 'player3': 100, 'player1': 99, 'player4': 63}

Answer 2

def score(match):
    players = {}
    for key in match:
        for player in match[key]:
            if player not in players:
                players[player] =match[key][player]
            else:
                players[player]+=match[key][player]
    return players

快速概览，如果玩家不在新字典中，则创建成员资格并将键指向该玩家的分数。否则将分数添加到该玩家的总分中

这里是您的问题的解决方案，

d = {'match1':{'player1':57, 'player2':38}, 'match2':{'player3':9, 'player1':42}, 'match3':{'player2':41, 'player4':63, 'player3':91}}
players = {}
for key, val in enumerate(d):
    #print val
    for ele,value in enumerate(d[val]):
        #print value
        if value not in players:
            players[value] = d[val][value]
        else:
            players[value] += d[val][value]

print players
highest = 0
highest_player = ""
for key, value in enumerate(players):
    if players[value]>highest:
        highest = players[value]
        highest_player = highest_player.replace(highest_player, value)
print highest_player,players[highest_player]

希望对你有所帮助。
