How to calculate of a footprint for the whole list of processes of a specific database

[Husamalbaghdadi]

Hi I would like to ask you please, how to calculate a footprint (e.g. GWI or resource use) for the whole list of processes of a specific database (e.g. ecoinvent or GaBi) using implemented Python, rather than doing the long calculations for all processes manually in openlca.

Thank you very much Husam
