[mostly ninja'd by Jeremy, but I 'd already typed this, and you might find PyCharm a useful editor.]

I'm not a Django expert, but from https://docs.djangoproject.com/en/4.1/topics/settings/ it sounds like they just import the settings.py as a module. This means it is run by the python language itself as a python program. It's not merely a data file describing the settings -- it's code that is run as a program. The name Q_CLUSTER refers to a variable and the = operator assigns the value on its right hand side to that variable/name on the left. (The curly braces enclose an object literal: a comma-separated list of name: value pairs.)

So, it will go with the second set of properties for Q_CLUSTER. There is no error; it's perfectly okay to store one value to the name/variable Q_CLUSTER and then later in your program assign a different value to the same name/variable. The code runs from top to bottom, so the second value assigned to Q_CLUSTER is what remains in memory after these settings have been processed.

If you would like a tool that *would* complain, take a look at PyCharm Community Edition (no cost... not sure it's free-libre, though) from JetBrains: https://www.jetbrains.com/pycharm/download/#section=windows

When I paste your snippet into an PyCharm editor window, it puts a warning highlight behind the second instance of Q_CLUSTER. When I hover over that, a pop-up tooltip cautions that I "Redeclared 'Q_CLUSTER' defined above without usage' and I can click on it for an extended explanation.

(It also caught that you have three spaces before 'retry' and then four before 'timeout'... in some places in python syntax, inconsistent indentation is an error, but not here)

Hope that's helpful.

Does mailman-web do sanity checks in settings.py?

Suppose I have the following:

Q_CLUSTER = { 'name': 'mailman3-web', 'workers': 8, 'retry': 360, 'timeout': 300, 'save_limit': 100, 'orm': 'default', }

Q_CLUSTER = { 'retry': 320, 'timeout': 300, 'save_limit': 100, 'orm': 'default', }

Which setting will it go with?

And why doesn't it complain about a setting being made 2x?
