[aspect-devel] read parameter file with Python

[Marine Lasbleis]

Thanks for the info!

A JSON file would definitely do it. 
I’ll have a look how to output it. 
I also usually name my folders with the parameters I’m modifying, but experience showed that later on, I may be interested in other parameters I forget to add in the folders names, so using the complete output parameters (and being able to access any parameter later on) would be the best. 

The statistics file with more added parameter may also be a good option, especially as I will have a couple of parameters evolving with time later on.

About the statistics file, I’m not sure how much other use Python… But so: at first, I use simply readlines(), but it is very slow for large files, so now I’m using pandas (pd.read_csv()), with a little trick for the header. Not sure if this is the best option, so let me know if you know any other one! The long header is definitely a problem with the different techniques I tried. (especially as it can’t be used as column names easily)

Best, 
Marine
