Python's method of automatically connecting to SSH

This article illustrates an example of how Python automatically connects to SSH. Share with you for your reference. The specific implementation method is as follows:

#!/usr/bin/python
#-*- coding:utf-8 -*-
import sys, time, os
try:
  import pexpect
except ImportError:
  print """
    You must install pexpect module
  """
  sys.exit(1)
addr_map = {
  'v3' :('root@192.168.1.162', 'sina@2009'),
  'dev':('test016@192.168.1.136', 'test016'),
}
try:
  key = sys.argv[1]
  host = addr_map[key]
except:
  print """
    argv error, use it link
    jssh v3, v3 must defined in addr_map
  """
  sys.exit(1)
server = pexpect.spawn('/usr/bin/ssh %s' % host[0])
server.expect('.*ssword:')
server.sendline(host[1])
server.interact()

I hope this article has helped you with your Python programming.
