''' Before an except clause’s suite is executed, details about the exception are stored

in the sys module and can be accessed via sys.exc_info(). sys.exc_info() returns a

3-tuple consisting of the exception class, the exception instance and a traceback

object identifying the point in the program where the exception occurred. sys.exc_info()

values are restored to their previous values (before the call) when returning from

a function that handled an exception.'''

''' If no exception is being handled anywhere on the stack, a tuple containing three None

values is returned. Otherwise, the values returned are (type, value, traceback).

Their meaning is: type gets the type of the exception being handled

(a subclass of BaseException); value gets the exception instance

(an instance of the exception type); traceback gets a traceback object which

encapsulates the call stack at the point where the exception originally occurred.'''
