Thank you for the reply. I tried that, I am trying to do this. The context is I am trying to find mapk ( k = 3 ) for this list. A, B , C, D and E are product names.
If I am trying manually I will do something like this. TRUTH = [[A], [B,C], [A], [D,E]] and if my prediction is : PRED=[[B,A, D], [A,C,B], [A,B,C], [B,D,E]] map3(truth, pred, 3) How do I convert my input truth values in the TRUTH format. Should I be looking for "boolean indexing" for this case. id A B C D E 100 1 0 0 0 0 101 0 1 1 0 0 102 1 0 0 0 0 103 0 0 0 1 1 ''') -- https://mail.python.org/mailman/listinfo/python-list
