Python Exception Hierarchy

👉Every Exception in Python is a class.

👉All exception classes are child classes

     of BaseException, i.e., every exception

     class extends BaseException either

     directly or indirectly.

👉Hence, BaseException acts as the root

      for the Python Exception Hierarchy.

👉Most of the time, being a programmer, 

     we have to concentrate on Exception

     and its child classes.

Customized Exception Handling by using  try-except

👉It is highly recommended to handle

     exceptions.

👉The code which may raise an exception is

     called risky code, and we have to take      

     risky code inside the try block.

👉The corresponding handling code we

      have to take inside the except block.
