Idiomatic Python: use lists instead of tuples where appropriate

Description

Currently most of the documented lists are actually tuples. This is uncalled for and not really pythonic.

Python authors have already stated that tuple was not a frozen list. Let's stick to using tuples where tuples fit, eg. where a namedtuple could be used instead but would be an overkill.

I'm concerned about the backwards compatibility of this patch - I know in a number of my projects I import the default value from global settings and combine it with another list/tuple of my own appropriately. It's a minor issue, but I'm not sure it's worth breaking things for the sake of a little properness. Nothing is broken at the moment.

@mjtamlyn, can you provide a case that no longer works?

comment:5 by Tim Graham, 11 years ago

I had similar concerns. For example:

from django.conf.global_settings import TEMPLATE_CONTEXT_PROCESSORS
TEMPLATE_CONTEXT_PROCESSORS + ('myapp.myprocessor',)

After this change, the above code would throw an error: TypeError: can only concatenate list (not "tuple") to list.

Like Marc and Tim, I don't think the disruption caused by this change is really worth it.
