I'm a python developer, and a big fan of the features with gradual typing etc. This article really highlights for me though, how python has very much changed from the language it was even 5 years ago.

Initially, the celebrated feature of python was that it allowed easy and fast development for newcomers. There was a joke a long the lines, "I learned python, it was a great weekend".

As much as I like python's type system (and wouldn't want to see them ever go way!), part of me wonders if moving into a world where hello-world can look like this, is a world where python is no longer the "lean in a weekend" language:

     from typing import Annotated
     import typer
     
     app = typer.Typer()
     
     @app.command()
     def main(
          name: Annotated[str, typer.Option("--name", "-n")],
     ) -> None:
         """Prints out 'HELLO {name}!!' (name upper cased) to the console"""
         print(f"HELLO {name:upper}!!")
     
     if __name__ == "__name__":
         app()

(obviously the example is silly, and I know this is a lot more than you need to do, hopefully you get my point though!)
