title: How to get create your real-work simple server on Python
body: <p>I am writing simple app with using Python socket lib.
  I wrote a simple Server and Client. On my local computer is works. But I want to send Client app to my friend. The problem is here:</p>
  
  <pre><code>Server:
  HOST = "127.0.0.1"
  port = 3010
  serverSocket.bind((HOST, port))
  
  Client:
  HOST = "127.0.0.1"
  port = 3010
  clientSocket.connect((HOST, port))
  </code></pre>
  
  <p>When this apps run on my local machine it is ok. But what HOST should be to make possible communicate with MY computer from other computer?</p>
