TCP/IP client script help - Rehan11 - Jan-12-2019

Client script
Here's simple code to send and receive data by TCP in Python:
#!/usr/bin/env python

import socket

TCP_IP = '192.168.0.12'
TCP_PORT = 5004
BUFFER_SIZE = 1024
MESSAGE = "How are you!"

s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((TCP_IP, TCP_PORT))
s.send(MESSAGE)
data = s.recv(BUFFER_SIZE)
s.close()

print ("received data:", data)
I want to send the message "How are you!" continuously to the server. the server would respond either "I am fine" or "I am not okay"

if the server responds " I am fine " do nothing but if the server responds "I am not okay" then print the message " I will take care of you"

How to make python client script for the above purpose?

You currently send it once. To send it repeatedly, use a loop.
You currently get and display the response. Use an if statement to check it's result.

Thanks nilamo

Do you mean like this

#!/usr/bin/env python
 
import socket
 
TCP_IP = '192.168.0.12'
TCP_PORT = 5004
BUFFER_SIZE = 1024
MESSAGE = "How are you!"
 
s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
s.connect((TCP_IP, TCP_PORT))
while True:
      s.send(MESSAGE)
      data = s.recv(BUFFER_SIZE)
      data2 = data	  
	  if data2 != data:
	     print(" I will take care of you") 
	  
s.close()
 
I know I have to store and compare previous and present string

does it make any sense ?
