Python面向切面编程-语法层面和functools模块

标签：python面向切面编程

1，Python语法层面对面向切面编程的支持(方法名装饰后改变为log)

__author__ = 'Administrator'

import time

def log(func):
    def wrapper(*args):
        start = time.time()
        func(args)
        end =time.time()
        print 'func used time is :', end - start
    return wrapper

@log
def reg(args):
    
     print 'welcome %s ' %(args[0])
        
reg('joeyon','123456')      

import time
from functools import wraps

def log(func):
    @wraps(func)
    def wrapper(arg1,arg2):
        start = time.time()
        func(arg1,arg2)
        end =time.time()
        print 'func used time is :', end - start
    return wrapper

@log
def reg(username,pwd):
    
     print 'welcome %s ' %(username)
        
reg('joeyon','123456')
