How can I find out the current network load (Mac OS)?

Question

Python

Please help me come up with an algorithm / maybe there is some ready-made command in order to find out the current network load on Mac OS, then you need to work with this variable programmatically (Python, PHP, Shell, something else). For example - a torrent client is currently downloading 200-300 kb / s, a YouTube video is being loaded in Chrome and consuming another 300 kb / s. How to collect all this in total in one variable (500-600 kb / s)?
What you need: Yota (a mobile operator from Russia) has a function in its personal account to dynamically change the tariff and cost parameters, I would like to write a demon that would monitor my current "high-speed needs" and, depending on this, turn on the desired tariff, maximum savings. I found a Python script on GitHub in which you can dynamically change the speed through the console, passing the necessary one as a parameter, I would like to automate.
