Maybe we just need to agree to disagree here. I don't see
It's not pretty, but this is what seems to work... I'd be happy hear more
about a better approach... I like the idea of using a list, but ran into
troubles with min and max, maybe I don't entirely understand the lambda
function, but when I tried a list, I got an error that min() has no optional

First off, here is the code I am working with so far.

Hello,
I'm using the code below to select the closest dates in a dictionary of
dates, to selected dates (Tstart, Tend)... Now, I need to get all the dates
(slice) from the dictionary in between the two dates TstartNew and TendNew.
Basically, I need to know what the 'index' is for them in the in t

You could do it but it would be easier to change it a little
because the original games prompts etc betray its internal
structure. You can just get the objects to return their attributes

You said I can use the procedural program as a program "requirement"
because it defines I/O. Even though the OOP program will have the

Your game is perfectly within reach of a novice programmer. Board
Games are often used as the final project for early courses at Georgia
Tech that many people take who aren't going to be programmers for a
living. You're also going to chop up some code you didn't write and
make it do something funda

Hi all,
Returning to python after a brief affair with C++, I have the following code ...
if (items.has_keys('snapshot_interval')):
self.snap_init[i] = items['snapshot_interval']
else:
self.snap_init[i] = 0
