I use the following in OS-X, should be very similar in Windows.
import subprocess
ping_result = subprocess.Popen(['ping', '-c1', '-t1', self.target_IP],
stderr=subprocess.PIPE, stdout = subprocess.PIPE).communicate()[0]
self.target_IP is a string containing the IP address, which is defined
elsewhere.
ping_result contains the complete returned string from the ping command. Note
the -c switch (count = 1 ping packet) and the -t switch (force exit after one
second).
you will have to parse the returned string to extract the stats.
