我可以在Python中将两个装饰器组合为一个吗？ [英] Can I combine two decorators into a single one in Python?

问题描述

有没有办法在Python中将两个装饰器组合成一个新的装饰器？

Is there a way to combine two decorators into one new decorator in python?

我意识到我可以将多个装饰器应用于一个函数，但是我很好奇

I realize I can just apply multiple decorators to a function, but I was curious as to whether there's some simple way to combine two into a new one.

推荐答案

更通用一些：

def composed(*decs):
    def deco(f):
        for dec in reversed(decs):
            f = dec(f)
        return f
    return deco

然后

@composed(dec1, dec2)
def some(f):
    pass

等同于

@dec1
@dec2
def some(f):
    pass
