Would you mind being so kind as to explain what it is about then? Saying something is wrong without saying why or how is just noise.

  She's talking about Python being a dynamically-typed & interpreted language, making it "simple and so ergonomic to use [for] new developers" and "[suitable] to exploring", but "[less suitable] to long-term, stable systems". It's not specific to Python. Big projects written in dynamically-typed languages are hard to reason about and maintain. And the lack of compiler makes it harder to catch typos, incorrect types, non-handled null/None values, etc… before runtime.

    > And the lack of compiler makes it harder to catch typos, incorrect types, non-handled null/None values, etc… before runtime. linters exist for a reason. it isn't so clear-cut any more, either, with type hints in python that can now be enforced, although honestly i haven't experimented with that much, since i don't think it's necessary. > Big projects written in dynamically-typed languages are hard to reason about and maintain. let's not pretend statically-typed languages are always easier to reason about. throw enough interfaces into a Java project or templates into a C++ project and they're also hard to reason with. you may have had bad experiences with dynamically-typed stuff, or simply prefer static typing, but these seem more opinions than facts. and again, i'm happy to argue that it's hard to predict the future. many projects benefit more from the increased velocity dynamically-typed languages offer at the start (the exploration if you will), than trying to build a system for millions of users from the start. that probably makes sense for FAANG projects, but for most it's overkill. so the suitability towards "long-term, stable systems" is half true. hindsight can be powerful, but can also be misleading.
