I'm developing a web system and based on some patterns I've seen
elsewhere, I made a single file (model.py) to hold all of the
functions and classes that define the model porition of the
application. Hence the code in the controller looks like:
import model
def Display(req,id) :
# ....
It works and things make sense to me. Yet, I feel uneasy that my
model.py file is starting to approach 500 lines. What's the best
practice or community opinion on this? Do I keep everything in a single
file or do I start dividing things into separate files?
TIA

several of my programs are thousands of lines long, and i don't think
they're extravagantly large.
i'd say you should use modules the same way you use classes and
functions: to separate code logically.
if it makes sense to think of a group of statements as a function, you
make it a function. if it makes sense to think of a group of functions
as data as a single object, you make a class. if it makes sense to
think of a collection of classes and functions and data as a collective
unit, make a module. and so on for packages.
if it makes sense for a single function to be hundreds or thousands of
lines long, so be it.
follow the modern poet's rule: ignore restrictions that don't make
sense, and follow closely the restrictions you choose. dh****@gmail.co m wrote:

It varies by project and preference. Working with very large files
can get cumbersome, but having a lot of small files means higher
amounts of editing hassle and more junk to keep track of.
As a personal opinion, I'd say just try to keep your functions small
and understandable, and don't worry about file size until the files
start getting inconvenient to edit. I find 1000-2000 lines is a
reasonable file size. This thread has been closed and replies have been disabled. Please start a new discussion. Similar topics | |

I proposed python as the main language for our next CAD/CAM
software because I think that it has all the potential needed
for it. I'm not sure yet if the decision will get through, but
something I'll need in this case is some experience-based set
of rules about how to use python in this context.
For example... is defining readonly attributes in classes
worth the hassle ? Does duck-typing scale well in complex

Hi,
I want to add unit tests in my application using NUnit.
At first, I thought to add unit tests in the class that is tested, enclosed
in a conditional attribute to remove these unit tests from release code.
Though, there is (at least) 2 problems working like that :
1) the class can becoming very large if there is a lot of tests
2) when releasing, the NUnit dll should not be needed => it should not be
referenced.

I am unable to find appropriate documentation on the type promotion of bit-fields when using the generalised comparison operator "<=>".
