python多参数多功能多个装饰器

下面展示多参数多功能多个装饰器
具体代码如下：

# Author:HY
import time
import math
import sys
def deco(func):
    def wrapper(*args,**kwargs):
        startt = time.time()
        time.sleep(0.00000001)
        func(*args,**kwargs)
        endt = time.time()
        f=str(func)[1:12]
        print("The %s runs %s" % (f,(endt - startt)))
    return wrapper

def jdt(func):
    def wrapper(*args,**kwargs):
        func(*args,**kwargs)
        for i in range(100):
            sys.stdout.write("%s" % i)
            sys.stdout.write("% ")
            sys.stdout.flush()
            time.sleep(0.1)
    return wrapper


def defunc(func):
    startt=time.time()
    func()
    endt=time.time()
    print("The func runs %s"%(endt-startt))
    # return func

@jdt
@deco
def f1(a,b):
    print("This is 周长!")
    print("C=",2*(a+b))

@deco
def f2(r):
    print("This is 面积!")
    pai=math.pi
    print("S=",pai*r*r)

@deco
def f3(a,b,c):
    print("This is 体积!")
    print("V=",a*b*c)

f1(1,2)
f2(1)
f3(3,4,5)

输出结果如下：

This is 周长!
