Hi, I have 2 lists a = [(4, 1), (7, 3), (3, 2), (2, 4)] b = [2, 4, 1, 3]
Now, I want to order _a_ (a[1]) based on _b_. i.e. the second element in tuple should be the same as b. i.e. Output would be [(3, 2), (2, 4), (4, 1), (7, 3)] I did the same as follows: >>> l = len(a) * [None] >>> for (k, v) in a: ... for i, e in enumerate(b): ... if e == v: ... l[i] = (k, v) This works, but the code -for python- looks very kludgy. I thought for ~2 hours to see whether I can do it in a line or 2, but I cannot seem to find a mechanism. Can someone help me out? -- http://mail.python.org/mailman/listinfo/python-list
