In MATLAB you can do behave such as:

fldname = 'cost'; 
box.(fldname)  = 5;

Then box.cost will have 5

I would also want to read from box with something like the following:

val = box.(fldname) #where fldname is set somewhere else like above

Is there a similar ability in Python?

You can't set new attributes on every object, but where you can, `setattr` will achieve your goal. – DSM Sep 11 '14 at 19:10
For reading, `getattr` can be used. – DSM Sep 11 '14 at 19:48
Great thanks for the help – sedavidw Sep 11 '14 at 19:49
