This allows catching Exception to continue to work in the common case of catching all exceptions that should be caught. Direct inheritance of BaseException should only be done in cases where an entirely new category of exception is desired. But, for cases where all exceptions should be caught blindly, except BaseException will work.

class Exceptions typically leave the current codepath right away and make use of automatic cleanup mechanisms (e.g. there is no need to manually clean up the stack). In order to throw an exception from the VM you usually only need to free the opcode operands and invoke HANDLE_EXCEPTION(). Exceptions have the additional advantage of providing a stack Raise an exception. As a Python developer you can choose to throw an exception if a condition occurs.

Raise an exception. As a Python developer you can choose to throw an exception if a condition occurs. To throw (or raise) an exception, use the raise keyword.

In Python, all exceptions must be instances of a class that derives from BaseException. In a try statement with an except clause that mentions a particular class, that clause also handles any exception classes derived from that class (but not exception classes from which it is derived). public class BaseException extends java.lang.Exception.

If the exception thrown were of the class customException and there were no customException catch, only the base exception catch, the exception would be handled there. Re-throwing Exceptions Sometimes, when an exception is thrown, you may wish to handle it differently than the standard way. except BaseException: to point out that you know what you’re doing. All exceptions stem from BaseException, and those you’re meant to catch day-to-day (those that’ll be thrown for the programmer) inherit too from Exception. // See your network administrator or try another path.
