This fails on my Python 3.8.12 with:

❯ scripts/run_all.py
Traceback (most recent call last):
  File "scripts/run_all.py", line 12, in <module>
    def run_py_example(path: str, args: list[str] = []) -> None:
TypeError: 'type' object is not subscriptable

I assume you are using a newer Python?

Of course, this being python, the linter doesn't catch this 🤦 (Python 3.8 is our minimum supported version, and what is used on CI)

What we do elsewhere is from typing import List and then args: List[str].

[jprochazk]

Yeah, I'm currently on 3.10. I guess I'll also downgrade to 3.8 to catch this stuff earlier.

$ python --version
Python 3.8.16

Nicely done!
