How do I change some values obtained from the list to the values I want with a smart way?

Hi @jamestwebber,
Thanks for your advice and sorry for the late reply.

@jamestwebber

I’m confused: what is the relationship you want between the devices and the output? Can you post a full list of inputs and desired outputs?

The information shown on the image all obtained in the path /sys/bus/pci/device/BDF_id/… as following picture to the MAC address.

So I was thinking maybe I can get the port index I want in the path.
But because of there is no any information can let me use for displaying as port index so I fail.

@jamestwebber

for i, pci_dir_path in enumerate(list_of_pci_dir_paths):
    port_index = i % 8  # port_index will cycle through 0..7
    
    ... do whatever it is you are trying to do ...

This solution is suitable for solving the problem of the images.
But if the port index I wanted is displayed as follow, this solution won’t work.

I had change the way to modify the result in a file, if you are interested, please feel free to discuss it together.
