Python-oriented aspect programming-syntax level and Functools module

1,python syntax plane support for aspect-oriented programming (method name changed to log after decoration)

__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 module support for facets (the method name is not changed after decoration)

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)
