This makes a and b both lists Having read some other errors that you are having, you need to make sure that these items are numeric and not string data for row in rdr: a.append(int(row[0])) b.append(int(row[1])) > # using lists of values for length in [a]: > for orientation in [b]: > makeimg(length, orientation) This puts list a inside another list, and puts list b inside another list, and then passes the whole of lists a and b in the first call to makeimg. makeimg expects 2 integer parameters on each call, not two lists! As you have already created lists, you don't need to wrap them inside another list. # using lists of values for length in a: for orientation in b: makeimg(length, orientation) -- Denis McMahon, denismfmcma...@gmail.com -- https://mail.python.org/mailman/listinfo/python-list
