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, '*'))
