简单的ping实施 [英] Simple ping implementation

问题描述

我需要简单的ping操作，如果目标不可达，它将返回一些浮点数或无.我正在使用Python 3和Windows，并且不想使用标准输入法，因为我必须从shell解码字节并解析结果.我对ICMP协议的实现一无所知，因此准备使用库是最好的选择.

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.
