How to monitor per-process network usage in Python?

I'm looking to troubleshoot my internet issue so I need a way to track both my latency and which application is using how much network bandwidth.

I've already sorted out checking latency, but now I need a way to monitor each process' network usage (KB/s), like how it appears in Windows Task Manager.

Before you suggest a program, unless it's able to record the values with a timestamp then that's not what I'm looking for. I'm asking for a Pythonic way because I need to record the network bandwidth and latency values at the same time so I can figure out if a specific process is causing latency spikes.

So here's the info I need:

Time | Process ID | Process Name | Down Usage | Up Usage | Network Latency |

Also, please don't link to another Stackoverflow question unless you know their solution works. I've looked through plenty already and none of them work, which is why I'm asking again.
