sic idea is to make a small data structure of your own (just the
dictionary runner_lists in the example above) and fill it in with the
infomation you care about in a convenient and useful shape. Then just return
the data structure.
The actual data structure will depend on what you need to do with this later.

You can see I've given a distinctive name to "join", which would otherwise be

That's the beauty of offering untested code: I don't have to find and fix my

t;s".decode() returns the string value "s", and Python is
internally deciding to reuse the existing "s" from the left half of your
comparison. It can do this because strings are immutable. (For example, "+=" on
a string makes a new string).
Hoping this is now more clear,

tive. I'm not a big believer in "egoless programming" as my ego is
bound up in my desire for quality, but a consequence of that is that criticism
_is_ received personally, and therefore it should be as well phrased as
feasible.
Before signing out, let me hark to some words from the glorious film "Harvey":

Usually I define a small class for this
kind of thing and keep all the state in class instances. That way it can scale
(keeping multiple "states" at once).
However, it does depend on your particular situation. I find situations where I
want to directly change "global" valu

thing is an issue, but the language doesn't require it, and one could change
