Python dependency management is quite adequate for teaching - all you need to know is how to pip-install packages, really. The real headaches don't show up until you have a large app with lots of dependencies.

The other thing about Python is that, because it's already so popular for teaching, it has an ecosystem of tools around that. E.g. it has turtle graphics in the standard library (!), which is a very good way to explain loops, recursion etc for visual learners. There's also IDEs like https://thonny.org/ that visualize program execution step-by-step.
