Modularity of code is difficult for sure and is kind of an art. To do
it best you will have to read about and implement some of the Design
Patterns. There are many but some of the ones that I have leaned
towards over time are Composition over inheritance, Message Passing
Interfaces, Mediator, and

practical use for controlling user interfaces via a message passing.
Does any one have any links to such an example? I would be most
grateful. Thank you.

Hi,
So what I am working on is taking a csv file and only taking 2 columns from
the spreadsheet and out putting that to a text file. Then taking those two
columns and organize them by product(key) and outputting the
description(values) that are associated. Some products have a lot of
duplicate desc

No, never expect anything from a given programming language. What did
you not understand about this

Many thanks!

Pythonic style/preference question: For strictly Python 3 code, is
there any preference for

pass
versus the more explicit
class MyClass(object):
pass
