def funA(desA):
print("It's funA") def funB(desB):
print(desB( ))
print("It's funB") @funA
@funB
def funC():
print("It's funC")
return "return c"

结果:

Python 修饰符@用法-LMLPHP

执行顺序是funA(funB(funC))

1、先执行funC 结果 "return c" 放入到funB()运行  此时输出为  It's funC

2、funB(desb)   运行输出为   return c    It's funB

3、funA(desA)   运行因为desA 无返回值为None,所以输出为 It's funA
