python exception stack trace

considered unhandled, and the Python interpreter displays a trace return message and exits. The try-except statement that Python provides to programmers is to better track potential bugs and prepare the logic to handle exceptions in code, a mechanism that is hard to implement in other languages, such as C. It is designed to reduce the number of errors in the pro
