title: socket.error: [Errno 32] Broken pipe
body: <p>I wrote a client-server python program where the client sends a list to the server, the server receives the array, deletes the first two elements of the list and sends it back to the client. 
  There is no problem with the server receiving the list. But when the server wants to send back the edited list, it is showing error: 
  <code>socket.error: [Errno 32] Broken pipe</code>.
  The client.py and the server.py are running from different machines with different ip.  I'm posting the code for the client.py and server.py below:</p>
  
  <p>Client.py</p>
  
  <pre><code>import socket, pickle
  HOST = '192.168.30.218'
  PORT = 50010
  s = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
  s.connect((HOST, PORT))
  arr = ['CS','UserMgmt','AddUser','Arnab','Password']
  data_string = pickle.dumps(arr)
  s.send(data_string)
  data = s.recv(4096)
  data_arr1 = pickle.loads(data)
  s.close()
  print 'Received', repr(data_arr1)
  print data_arr1;
  </code></pre>
  
  <p>Server.py:</p>
  
  <pre><code>import socket, pickle;
  HOST = '127.0.0.1';
  PORT = 50010;
  s= socket.socket(socket.AF_INET, socket.SOCK_STREAM);
  s.setsockopt(socket.SOL_SOCKET, socket.SO_REUSEADDR, 1);
  s.bind(('',PORT));
  s.listen(1);
  conn, addr = s.accept();
  print 'Connected by' , addr;
  data_addr = list();
  while 1:
          data = conn.recv(4096);
          if not data: break;
          data_addr = pickle.loads(data);
          print 'Received Data',  repr(data_addr);
          print data_addr;
          data_addr.pop(0);
          data_addr.pop(0);
          print data_addr;
          data_string1 = pickle.dumps(data_addr);
          s.send(data_string1);
          break;
  conn.close();
  socket.shutdown();
  socket.close();
  </code></pre>
  
  <p>The entire error msg is:</p>
  
  <pre><code>Traceback (most recent call last):
  File "server.py", line 22, in &lt;module&gt;
  s.send(data_string1);
  socket.error: [Errno 32] Broken pipe
  </code></pre>
  
  <p>How do I fix this problem so that the client can receive the edited list from the server without any error ? 
  Thank You in advance.</p>
