Using a csv file as an input to create an outputs list

Grasshopper

I’m doing a project where I need to generate max deflection value for thousands of beams with different cross sections. So far, I have succeeded in generating this for single beams using Karamba 3D and I was able to export the output as a CSV file.

My question is: If I had a CSV file with thousands of inputs, which I would link to the grasshopper components, would there be a way to cycle through the rows of the CSV file, (in the style of a for loop, for example), and produce a list of corresponding outputs (perhaps to a panel component)? If so, how would I go about creating such a for loop and ensuring that my output doesn’t get overwritten with each iteration?

Thanks in advance

I’m sure it’s possible with the native file reader in Grasshopper. It’s straightforward in GHPython in my experience - e.g.:

open(file_path 'rt') as f: 
    for line in f: 
        row_entries = line.split(',')
        # process line or row_entries
