Re: Getting sorting order

I cannot find anything on this:
I have a few lists, and would like to sort one of them (sorting-master
list).
Then I would like to sort all other lists according to how the first
one was sorted (sorting-slave lists).

Is there a standard way to do that?
From what I know sort() and sorted() do not return the order of
sorting.
Maybe I have to write some more code.

Or provide a better explanation and an example. Do you mean something like
this?

master = [1,3,5,2,4,6]
slave = [1,2,3,4]
slave.sort(key=master.index)
slave
[1, 3, 2, 4]

It can be made more robust and efficient with an intermediate dictionary:

master_dict = dict((v, i) for i, v in enumerate(master))
slave = ["yadda",1,2,3,6,42]
slave.sort(key=master_dict.get)
slave
['yadda', 42, 1, 3, 2, 6]
