def extrafun(hi):
    if hi>10:
        def decorator(func):
            def wrapper(x):
                print('before decoraoting')
                func(x)
                print('After decoraoting')
            return wrapper
        return decorator
    else:
        def decorator(func):
            def wrapper(x):
                print('구분어떻게해?')
                func(x)
                print('구분어떻게해?')
            return wrapper
        return decorator
@extrafun(12)
def newfunc(c):
    print("this is new function")

@extrafun(9)
def newfunc2(c):
    print("나는 바보다")

newfunc(12)

装饰之前这是新功能装饰后

newfunc2(9)
