title: Python working with sockets the method recv
body: <p>I'm programming in python with sockets server-client. When I recieve as the server from the client by using the receive function:</p>
  
  <pre><code>someSocket.recv()
  </code></pre>
  
  <p>Is there any possibility that receives an unknown object? Or must I have to note the size of the data that I received from the socket?</p>
