Python套接字编程ConnectionRefusedError：[Errno 61]连接被拒绝

Question

This is my code for the server program:

import socket
soket = socket.socket(socket.AF_INET,socket.SOCK_STREAM)

HOST = "localhost"
PORT = 8011

soket.bind((HOST,PORT))
print("%s:%d server başlatıldı." % (HOST,PORT))
print("Kullanıcı bekleniyor.")
soket.listen(2)

baglanti,adres = soket.accept()
print("Bir bağlantı kabul edildi.", adres)

baglanti.send("Hoşgeldiniz efendim , hoşgeldiniz.")

data = baglanti.recv(1024)
print(data)

soket.close()

And this is for the client:

import socket
clientsocket = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
clientsocket.connect(("localhost", 8011))
clientsocket.send('hello')

Although I first start the server program and then the client program, I get this error:

Traceback (most recent call last):
  File "/Users/Esat/Desktop/Python/Softwares/socketto copy.py", line 3,  in <module>
    clientsocket.connect(("localhost", 8011))
ConnectionRefusedError: [Errno 61] Connection refused

Instead of localhost , it is better to use LAN (local) IP. You can get your local IP by running ipconfig (in Windows) or ifconfig (in GNU/Linux or Mac OS). Your local IP should be something like 192.168.1.x .
