As something of a surprise here, and as I got further into the code I'm
adding and modifying, the author did pretty much the dictionary
approach I was contemplating. I think I'll stick with the flow.

That's something for me to ponder, setattr. I'd rather not go off and
pick up on something like ConfigParser at this stage. I'd like to keep
this code somewhat simple and easy to understand, but yet have some
flexibility for changes.

Here's more detail. What I was hoping for was something like:
exec "=" dcon
This is fictitious of course, but would mean assign the values in [1] to
[0].
Yes, it would be easy to loop and assemble elements into a string that would
be executed by exec (or eval), or use some assignment line like your
example.
I have 30 or more of such assignments, and I would prefer not to have to
write them as assignments. The end purpose here is to produce a config file,
assign initial values, and change values. For example, the (text) file might
look initially like:
long 120.00
lat 39.00
year 2009
Do you know about the ConfigParser module?
http://docs.python.org/library/configparser.html
These would be written to the file by looping through dcon. Another time, I
might want to initialize these variables within the program, in the form
self.long = 120.00, etc.,
Ok, that is different than
long = 120.00
because the variable is an attribute of self. Try this, it will take
all the items in dcon and set them as attributes of self:
for key, value in dcon:
setattr(self, key, value)
