python的简洁是shell无法代替的

之前线上服务器分发配置都是用shell和expect脚本分发，脚本写了很长，上周换了ansible，现在自己用python写一个，就30行代码就可以实现需求，之前的shell写了快200行了，蛋疼，代码如下：

from multiprocessing import Process
import paramiko
import sys
file = sys.argv[1]
Username = "root"
Password = "123456"
Dest_Path = [

    "/data/x5online/%s" %file,
    "/tmp/%s" %file

]
Port = 22
def sftpPut(ip):
    try:
        s = paramiko.Transport((ip,Port))
        s.connect(username=Username,password=Password)
        sftp = paramiko.SFTPClient.from_transport(s)
        localFile = file
        for remoteFile in Dest_Path:

            sftp.put(localFile,remoteFile)
        print("%s put successful." %ip)
    except:
        print("%s not exits."%ip)
def ipProcess():
    for i in range(10,40):
        ip = '192.168.170.%s'%i
        p = Process(target=sftpPut,args=(ip,))
        p.start()
if __name__ == '__main__':
    ipProcess()

鸡汤一回，对python感兴趣了，学的才快。
