Exercise-3: Raising Exceptions using class

Here is an example related to RuntimeError. Here, a class is created that is a sub-class

from RuntimeError. This is useful when you need to display more specific information when an

exception is caught. In the try block, the user-defined exception is raised and caught in the except

block.

Try the following code:

class MyException(Exception):

pass

# MyException classinherits from the Exception class

raise MyException("Caught MyException")

What it does?

Now, add the try/finally block as shown below:

class MyException(Exception):

pass

# MyException classinherits from the Exception class

try:

raise MyException("Caught MyException")

finally:

print ("Done")

What it does?
