Q:

Simple ping implementation

I need simple ping that will return some float number or None if destination unreachable. I am using Python 3 and windows and don't want to use standart ping, cause i have to decode bytes from shell and parse results. I know nothing about implementation of ICMP protocol so ready to use library is the best choice.

A:

You could use a pure Python implementation like the following:
https://pypi.python.org/pypi/ping
or if you prefer this one:
http://www.python.org/~jeremy/python.html
and also take a look here, because they are discussing about the subject and you may find it useful:
python non-privileged ICMP
UPDATE
Without the need of patching for Py 3, a very simple example:
