Python Warnings

If you have ever tried to import the regex module or similar older code, you will know that Python has a robust system of warnings. These warnings help you to stay current and to ensure that the code you write today will not need to be rewritten in a year's time because your favourite module from ten years ago has been replaced by something like the re module. A complete list of Python's warnings can be found as part of Python's built-in Exceptions module (also available at python.org. I have posted some brief descriptions of them in the section on Python Modules (left).
