Hi,
I'm trying to write a script that will make a checkout from a svn repo and
build the result for the user. However, when I attempt to interface with the
shell it asks the user for their filename and I don't know how to capture this
with my implementation.
user = "XXX578"

I think this might be obvious? I have a base class which contains X

Steven,
You make some good points and I don't disagree with you. The code is
just a transfer from some older c++ code which had all sorts of
windows menus etc, which isn't required and would make it impossible
to run (again and again). It is not an especially complicated model,
and no doubt there

Sorry I should have added a little more example to help with clarity?
So after reading the .INI file I then initialise the objects I
described e.g.

Hi,
yes I read a .INI file using ConfigParser, just similar sections (in
my opinion) to make one object which i can then pass to different
classes. E.G.
class Dict2Obj:

The only purpose of this is that I think it is neater to reference
values

Hi,
I have a series of parameter values which i need to pass throughout my
code (>100), in C I would use a structure for example. However in
python it is not clear to me if it would be better to use a dictionary
or build a class object? Personally I think accessing the values is
neater (visually)

Hi,
I am translating some c++ code to python and just wanted to ask some
advise on structure. The original has everything declared globally and
nothing passed via function (I assume, but don't know, that this isn't
just standard c++ practice!). So given this, I have a pretty much
