一站式获取Netcat输出，处理和输入

说我做nc example.com 1234，它返回两个数字，并用换行符分隔，我必须将这些数字加在一起并将其输入回来。如果关闭连接，数字会发生变化，那么如何获得netcat的输出，对其进行数学运算并再次在一个连接中再次输入呢？

对于其他有相同问题的人，使用python套接字可能会更好。

一些示例代码可以解决此问题中的问题：

import socket

#AF_INET for IPv4, SOCK_STREAM for TCP (as opposed to UDP).
clientsocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)

# Tell the socket what IP and port number to connect to (must be in two brackets because it needs a tuple).
clientsocket.connect(('example.com', 1234))

#Recieve 1024 bytes of data.
data = clientsocket.recv(1024)

#Split the recieved data by newlines (returns a list).
data = data.split('\n')

#The first and second elements in our list should be the two numbers we need to add together, so we do that.
result = int(data[0]) + int(data[1])

#Send our result to the server.
clientsocket.send(str(result))

#Recieve any response from the server and print it to the screen.
data = clientsocket.recv(1024)
print data
