python decorator
1.常用方法，不带参数
def decator(func):
def inner_func(*args):
args = (i * 2 for i in args)
return func(*args)
return inner_func
@decator
def add(a, b, c):
return a + b + c
2.带参数：
class Dec(object):
def __init__(self, i):
self.i = i
def __call__(self, func):
def inner_func(a, b, c):
return self.i * func(a, b, c)
return inner_func
@Dec(2)
def abc(x, y, z):
print "function abc"
print (x, y, z)
return x + y + z
