Python socket program taking forever to run I tried to run following program on my Mac terminal. 

import socket
mysock = socket.socket(socket.AF_INET, socket.SOCK_STREAM)
mysock.connect(('www.py4inf.com', 80))
mysock.send('GET http://www.py4inf.com/code/romeo.txt HTTP/1.0\n\n')

while True:
    data = mysock.recv(512)
    if ( len(data) &lt; 1 ) :
        break
    print data;
mysock.close()


But it doesn't print anything and takes forever.  I tried some online platform to execute and got error message


  """Traceback (most recent call last): File "main.py", line 6, in
   mysock.connect(('www.py4inf.com', 80)) File
  "/usr/lib64/python2.7/socket.py", line 228, in meth return
  getattr(self._sock,name)(*args) socket.error: [Errno 110] Connection
  timed out"""


I put print statement after True: and before line "data = " and it prints statement there and then takes forever.

My Python environment is

"Python 2.7.10 (default, Jul 14 2015, 19:46:27)
[GCC 4.2.1 Compatible Apple LLVM 6.0 (clang-600.0.39)] on darwin"


And in different computer, it works.

Can anybody identify an issue?
Your program runs well on my MAC OS Mavericks (aka 10.9.5) with Python 2.7.5
It prints:

But soft what light through yonder window breaks
It is the east and Juliet is the sun
Arise fai
r sun and kill the envious moon
Who is already sick and pale with grief


I guess your program stuck while no answer was available within the TCP protocol time-out (either the server not responding or the link failing). If you want to avoid such case, you may put the "recv" statement in a separate thread and break after a time-out.
I found much help for this in this page: eli.thegreenplace.net/2011/05/18/code-sample-socket-client-thread-in-python/

Hope this helps.
