python3输出指定log信息

问题背景：

win10

python xxx.py > c:test.txt

上面这句只能把信息输出到test.txt，但是控制台看不到信息

要想在控制台和test.txt同时得到信息，如下操作：

官网源码：

import logging
logging.basicConfig(filename='log_examp.log',level=logging.DEBUG)#level=logging.DEBUG定义日志级别
logging.debug('This message should go to the log file')#输出级别level=logging.DEBUG
logging.info('So should this')#输出级别level=logging.INFO
logging.warning('And this, too'）#输出级别level=logging.WARNING

实战项目部分代码：

 1 def a(self):
 2         #with open("info.csv","r") as csvfile:
 3         with open("产品库模板(PLT导入)20161205_01.csv","r") as csvfile:
 4             #读取csv文件，返回的是迭代类型
 5             self.read = csv.reader(csvfile)
 6             for self.i in self.read:
 7                 if self.i[8] =="" or self.i[8]=="9" or self.i[8]=='项目编号':
 8                     continue
 9                 else :
10                     try:
11                         self.b(self.i)
12                     except Exception as e:
13                         print(e)
14             self.logging.info(e)
15 
16                     finally:
17                         print(self.i[8])
18           self.logging.info(self.i[8])
