I believe that marketing Python as "strongly typed" has the potential to confuse rather than educate. Python still crashes at runtime with these errors. It has nice error messages, but it still crashes, potentially in production. If you want to create your own "types", you'll have to add your own runtime checks. It's much more sane than JavaScript, but it's not strongly typed like Haskell. Python does not automatically coerce some built-in runtime values, that's it.
