title: How "File not open a bytes-like object is required, not 'int' " could be solved?
body: <p>I am writing a simple http server code using socket-network-programming as a way of connection between client-server nodes.</p>
  
  <p>simply, I used my browser as client and I coded server side using python. </p>
  
  <p>Now, everything seems right but when I run the server plus browser with specific path 'filename',like (http//:localhost:8080/filename) the browser gets my exception statement that is:
      404 Not Found</p>
  
  <p>I believe my trouble is here:
      client_socket.send("HTTP/1.1 200 OK\r\n\r\n".encode())</p>
  
  <p>The following error appears on server terminal console screen.</p>
  
  <pre><code>File not open  a bytes-like object is required, not 'int'
  </code></pre>
  
  <p>Any help or though is appreciated.</p>
