python输出日志文件_python将print输出的信息保留到日志文件中

具体代码如下所示：

import sys

import os

import sys

import io

import datetime

def create_detail_day():

'''

:return:

'''

# 年-月-日

# daytime = datetime.datetime.now().strftime('day'+'%Y-%m-%d')

# 年_月_日

daytime = datetime.datetime.now().strftime('day'+'%Y_%m_%d')

# 时：分：秒

# hourtime = datetime.datetime.now().strftime("%H:%M:%S")

# hourtime = datetime.datetime.now().strftime('time' + "%H_%M_%S")

detail_time = daytime

# print(daytime + "-" + hourtime)

# detail_time = daytime + "__" + hourtime

return detail_time

def make_print_to_file(path='./'):

'''

example:

use make_print_to_file() , and the all the information of funtion print , will be write in to a log file

:param path: the path to save print information

:return:

'''

class Logger(object):

def __init__(self, filename="Default.log", path="./"):

sys.stdout = io.TextIOWrapper(sys.stdout.buffer, encoding='utf-8')

self.terminal = sys.stdout

self.log = open(os.path.join(path, filename), "a", encoding='utf8')

def write(self, message):

self.terminal.write(message)

self.log.write(message)

def flush(self):

pass

sys.stdout = Logger(create_detail_day() + '.log', path=path)

print(create_detail_time().center(60,'*'))

if __name__ == '__main__':

make_print_to_file(path="/home/log/")

print('explanation'.center(80, '*'))

info1 = '从大到小排序'

info2 = ' sort the form large to small'

print(info1)

print(info2)

print('END: explanation'.center(80, '*'))
