python剑指网络

　　

>>> #获取hostname
... 
>>> host_name=socket.gethostname()
>>> print "%s" %host_name
SimilarFacedeMacBook-Pro.local
>>> #获取IP地址
... 
>>> socket.gethostbyname(host_name)
'192.168.30.120'

#获取远程机器的IP，类型于ping

        print("%s的IP地址:%s" %(remote_host,socket.gethostbyname(remote_host)))
    except socket.error,err_msg:
        print("%s: %s" %(remote_host,err_msg))
＃result:
