Say I have list of data as given in the example code below, I want to find all the unique categories (alphabetic letters) and unique IDs (numbers) and then produce a summary grid as manually entered in the "results". How could I code this?
Many thanks in advance, Jignesh data= ["A.1", "A.2", "A.3", "B.1", "C.2", "C.3", "D.4", "E.5", "E.6"] cols=[] rows=[] for item in data: i=item.split(".") if i[0] not in cols: cols.append(i[0]) if i[1] not in rows: rows.append(i[1]) print cols print rows results= [["Row/Col", "A", "B", "C", "D", "E"], [1, 1, 1, 0, 0, 0], [2, 1, 0, 1, 0, 0], [3, 1, 0, 1, 0, 0], [4, 0, 0, 0, 1, 0], [5, 0, 0, 0, 0, 1], [6, 0, 0, 0, 0, 1]] -- https://mail.python.org/mailman/listinfo/python-list
