Python字典 - 是否可以引用键值？

Question

我想按如下方式定义字典：

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

是否有允许我这样做的语法？

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'}

他们采用的格式为{ 密钥 : 值 for 变量 {{1} } 发生器 in

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

听起来您想要在分配给该密钥的值中使用您创建的密钥。是的，这是可能的：

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