打印日志的方法

import  time
def logger():
    time_format = '%Y-%m-%d %X'  #时间的一个格式
    time_current = time.strftime(time_format)    #strftime()函数接收以时间元组,并返回以可读字符串表示的当地时间
    with open('a.txt','a+') as f:
        f.write('%s end action
' %time_current)

def test1():
    print('in the test1')

    logger()
def test2():
    print('in the test2')

    logger()
def test3():
    print('in the test3')
    logger()

test1()
test2()
test3()
结果:
2018-04-25 09:06:18 end action
2018-04-25 09:06:18 end action
2018-04-25 09:06:18 end action
