如何从字典中找到最大值？

Question

嗨，这是我第一次使用python

我有字典：

players= {"Gehrig":{"atBats":8061, "hits":2721},
 "Ruth":{"atBats":8399, "hits":2873},
 "Williams":{"atBats":7706, "hits":2654}}

我想找到这三位玩家中点击率最高的一个。

所需的输出：

The most hits by one of the
players was 2873.

我的输入：

max(players.hits())
maximum = max(players,key=players.get)
max(players,key=players.get)

但是我只得到诸如以下的错误：

TypeError: '>' not supported between instances of 'dict' and 'dict'

我需要更改什么？

Answer 1

您要使用列表推导或生成器表达式仅遍历命中数：

players= {"Gehrig":{"atBats":8061, "hits":2721},
 "Ruth":{"atBats":8399, "hits":2873},
 "Williams":{"atBats":7706, "hits":2654}}

max(player["hits"] for player in players.values())
# 2873

如果您想查看哪个玩家的命中率最高：

max(players.keys(), key=lambda p: players[p]["hits"])
# 'Ruth'
