什么是实现枚举的最佳方式？在Python中？

在python中枚举的方法是什么？

Whats the recognised way of doing enumerations in python?

例如，我正在写一个游戏，希望能够上，下，左和右。我正在使用字符串，因为我还没有弄清楚python中的枚举是如何工作的，所以我的逻辑很像这样：

For example, at the moment I'm writing a game and want to be able to move "up", "down", "left" and "right". I'm using strings because I haven't yet figured out how enumerations work in python, and so my logic is littered with things like this:

def move(self, direction):
    if direction == "up":
        # Do something

我想用 Directions.up 替换up / p>

I want to replace "up" with something like Directions.up

推荐答案

class Directions:
    up = 0
    down = 1
    left = 2
    right =3
