VIP通道：一起学Python-通过python脚本进行批量telnet连通性测试

文档内容如下：

代码如下：

使用方法：

源代码如下：

import argparse
import os
import logging
import telnetlib









run_log = 'run.txt'
if os.path.exists(run_log):
    os.remove(run_log)
logger = logging.getLogger()
logger.setLevel('DEBUG')
BASIC_FORMAT = "%(asctime)s :%(levelname)s :%(message)s"
DATE_FORMAT = '%Y-%m-%d %H:%M:%S'
formatter = logging.Formatter(BASIC_FORMAT, DATE_FORMAT)
chlr = logging.StreamHandler() # 输出到控制台的handler
chlr.setFormatter(formatter)
chlr.setLevel('DEBUG')  # 也可以不设置，不设置就默认用logger的level
fhlr = logging.FileHandler(run_log) # 输出到文件的handler
fhlr.setFormatter(formatter)
logger.addHandler(chlr)
logger.addHandler(fhlr)
