Does python block httplib.HTTPConnection?

Question

I am not sure if the following code is a blocking operation in python:

import httplib
import urllib

def do_request(server, port, timeout, remote_url):
    conn = httplib.HTTPConnection(server, port, timeout=timeout)
    conn.request("POST", remote_url, urllib.urlencode(query_dictionary, True))
    conn.close()
    return True

do_request("http://www.example.org", 80, 30, "foo/bar")
print "hi!"

And if so, how could one create a non-blocking asynchronous HTTP request in python?

Thanks from python noob.

If you do not get to the length to prevent it, IOit will always be blocked.

Although you can perform asynchronous requests , you will need to make your program non-asynchronous. Async does not magically make your code non-blocking . It would be much easier to execute the request in another thread or process if you do not want to block the main loop.
