send get request python socket

import socket

target_port = 80  # create a socket object 
client = socket.socket(socket.AF_INET, socket.SOCK_STREAM)  
 
# connect the client 
client.connect((target_host,target_port))  
 
# send some data 
request = "GET / HTTP/1.1rnHost:%srnrn" % target_host
client.send(request.encode())  
 
# receive some data
