Define the following:
Throwing an exception
उत्तर
Throwing an exception means raising an exception.
Each time an error is detected in a program, the Python interpreter raises (throws) an exception. Exception handlers are designed to execute when a specific exception is raised.
Programmers can also forcefully raise exceptions in a program using the raise and assert statements. Once an exception is raised, no further statement in the current block of code is executed.
raise NameError
assert conditon, "message"APPEARS IN
