Maybe I am missing something but I think every dynamic typing system has this problem. I can't see what this has to do with Python and exceptions in general. It is not like there aren't statically typed languages with exceptions. This comment is an excellent critique of dynamic typed systems but it has nothing to do with exceptions.
The top-thread post was referencing Python, so I'm speaking in the Python domain specifically. Other dynamic languages have this problem also, and other languages with stronger static type guarantees do support exceptions.
I haven't encountered a language with dynamic typing of the sort Python has that doesn't also have a robust runtime exception system, and it'd be interesting to see what that looks like. There's probably some old flavors of BASIC that fit that mold (i.e. variable declaration is not required and also the only thing it offers for exception handling is setting a label to GOTO if a runtime exception occurs).
I guess I was too fixated on the exceptions part of your comment. You are right that due to Python's dynamic nature every line can turn into a runtime exception. Maybe it's because English is my second language but I couldn't understand that in your first comment.
