This week began to learn python, because the books are based on python2.x, and I installed the Python3.1, so the book is written in a lot of places do not apply to Python3.1, specifically on Google search on the 3.x and 2.x difference. It is hereby

Python uses an exception object to represent the exception, and if the exception object is not processed or snapped, the program will backtrack (traceback) execution.Exceptions can be raised automatically when an error occurs, or they can be raised
