11.3 Python 's raise exception handling
Whether it is python's automatic exception prompt or the try except exception handling statement, the python interpreter can automatically identify the exception triggering condition and make an exception judgment. When we need to achieve a reminder or abnormal effect under special conditions, even if the problem caused by this special condition belongs to the category of exception class BaseException (or Exception), this special condition may not trigger the interpreter. Judging to generate reminders or abnormal effects, that is, it cannot satisfy a special response. Therefore, at this time, we need to manually define the trigger conditions for abnormal generation.
