1，Python語法層面對(duì)面向切面編程的支持(方法名裝飾后改變?yōu)閘og)
__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')
2，functools模塊對(duì)面向切面的支持(方法名裝飾后不改變)
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')
