Available In:1.4 and later, with modifications over time The traceback module works with the call stack to produce error messages. A traceback is a stack trace from the point of an exception handler down the call chain to the point where the exception was raised. You can also work with the current call stack up from the point of a call (and without the context of an error), which is useful for finding out the paths being followed into a function. The functions in traceback fall into several common categories. There are functions for extracting raw tracebacks from the current runtime environment (either an exception handler for a traceback, or the regular stack). The extracted stack trace is a sequence of tuples containing the filename, line number, function name, and text of the source line. Once extracted, the stack trace can be formatted using functions like format_exception(), format_stack(), etc. The format functions return a list of strings with messages formatted to be printed. There are shorthand functions for printing the formatted values, as well. Although the functions in traceback mimi
