Java is dying and it paid off my mortgage

In Python isn’t that either this, for the first part of your sentence:

    students: list[tuple[int, Student]]

Or the second half and a more idiomatic structure:

    students: dict[int, Student]

From my experience, in the early programming classes that have switched from Java to Python, one of the reasons is the verbosity of Java. When you're trying to teach the basics of programming -- variables, some simple text IO, loops, functions, the structure imposed by Java can be a little overwhelming. I recall a lot of other students struggling with getting past all the little things you had to do just to get a "Hello World" written. Python is simpler to gradually introduce those concepts with, especially with very those who are just starting out. And especially when you're dealing with a quarter system, which many schools use, as a teacher you had a very limited amount of time to get through that sort of material.

IMO - verbosity, typing and compilation all get in the way of teaching a lot of the basics (logic, control flow, scope, functions, objects). With JS/Python, I think students can make small wins faster which helps them stay motivated. I say this as someone who watched 3 people decide CS wasn't for them after taking intro classes that focused on Java.

JAX-RS is basically Sinatra or Flask for Java. Not excessively verbose at all.

In France a local magazine for Linux enthusiasts has its cover on "Java as a language for scripting". Things are moving.
