Measuring ping latency of a server - Python

Question

I have a list of server IP addresses, I need to check if each one is online and how long the latency is.

I haven't found any straight forward ways of implementing this, and there seems to be a few problems in calculating latency accurately.

Any ideas?

If you are already comfortable with parsing strings, you can use the subprocess module to get the data you are looking for into a string, like this:

>>> import subprocess
>>> p = subprocess.Popen(["ping.exe","www.google.com"], stdout = subprocess.PIPE)
>>> print p.communicate()[0]

Pinging www.l.google.com [209.85.225.99] with 32 bytes of data:

Reply from 209.85.225.99: bytes=32 time=59ms TTL=52
Reply from 209.85.225.99: bytes=32 time=64ms TTL=52
