python - Python字典 - 是否可以引用键值？

Question

我想定义字典如下：

dict = {
    Player: $key.Name + " takes some action"
}

有没有一种语法可以让我这样做？

Answer 1

字典理解可能会有所帮助。

>> players = ["Mark", "Jack", "John"]
>> player_dict = {k: k + " takes some action" for k in players}
>> player_dict
{'John': 'John takes some action', 'Jack': 'Jack takes some action', 'Mark': 'Mark takes some action'}

它们采用{键值:变量for生成in器的形式}

Answer 2

class Player(object): 
    def __init__(self, name):
        self.name = name

p1 = Player("bernard")
p2 = Player("hoagie")

t = (p1, p2, ...)
d = {p: p.name + " something something" for p in t}

Answer 3

听起来您想在分配给该键的值中使用您正在创建的键。是的，这是可能的：

playerDict = {Player: Player + " takes some action"}
