Python面向切面編程-文法層面和functools模組

1，Python文法層面對面向切面編程的支援(方法名裝飾後改變為log)

__author__ = 'Administrator'import timedef log(func):    def wrapper(*args):        start = time.time()        func(args)        end =time.time()        print 'func used time is :', end - start    return wrapper@logdef reg(args):         print 'welcome %s ' %(args[0])        reg('joeyon','123456')      

2，functools模組對面向切面的支援(方法名裝飾後不改變)

import timefrom functools import wrapsdef 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@logdef reg(username,pwd):         print 'welcome %s ' %(username)        reg('joeyon','123456')
