import socket

target_host = "www.baidu.com"
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
data = "GET / HTTP/1.1
Host: baidu.com

"
client.send(data.encode())

# receive some data
response = client.recv(4096)

print(response)
