Python3 多個裝飾器的執行順序

執行環境是 python3

當用多個裝飾器修飾乙個函式時，離函式定義最近的裝飾器先被呼叫。

def make1(func):

return "111" + func()
def make2(func):
return "222" + func()
@make1
@make2
def hello():
return "hello world"
print(hello())

111222hello world

# @make1

# @make2
def hello():
return "hello world"
hello = make1(make2(hello))
print(hello())
