network programming - Ping a site in Python?

Question

How do I ping a website or IP address with Python?

Answer 1

See this pure Python ping by Matthew Dixon Cowles and Jens Diemer. Also, remember that Python requires root to spawn ICMP (i.e. ping) sockets in linux.

import ping, socket
try:
    ping.verbose_ping('www.google.com', count=3)
    delay = ping.Ping('www.wikipedia.org', timeout=2000).do()
except socket.error, e:
    print "Ping Error:", e

The source code itself is easy to read, see the implementations of verbose_ping and of Ping.do for inspiration.
