Give the exception classes present in Django.

An exception is a rare occurrence that causes a program to fail. Django has its own exception classes to cope with this circumstance, and it also supports all fundamental Python exceptions. some of the exception classes are listed below:

• MultipleObjectsReturned – If just one item is anticipated but many objects are returned, this error is thrown by the query.
• ViewDoesNotExist – When a requested view does not exist, Django.URLs raise this exception.
• PermissionDenied – It’s triggered when a user doesn’t have the necessary permissions to perform the requested activity.
• SuspiciousOperation – The query throws this error if only one item is expected but several things are returned.
• ValidationError – It’s triggered when data validation fails on a form or a model field.
• FieldDoesNotExist – It raises when the requested field does not exist.
• ObjectDoesNotExist – The base class for DoesNotExist exceptions.
• AppRegistryNotReady – It is raised when attempting to use models before the app loading process.
• EmptyResultSet – If a query does not return any result, this exception is raised.
