I am new to Python, with some experience in Java, C++ and R. Writing in other languages I usually check the type and values of function arguments. In the Python code examples I have seen this is rarely done.
Questions: 1) Is this because it would be "unpythonic" or just because the examples are not really production code? 2) If I still want to check the type of my arguments, do I a) use type() or is instance() to check for type? b) use assert (I guess not), raise a ValueError, or sys.exit()? (I noticed that raising a ValueError does not stop execution when I am running the Interactive Interpreter under PTVS, which I find inconvenient, but it does stop execution when running the code non-interactively.)
