All instances in Python must be instances of a class that derives from BaseException. Two exception classes that are not related via subclassing are never equivalent, even if they have the same name. The built-in exceptions can be generated by the interpreter or built-in functions.

There are several built-in exceptions in Python that are raised when errors occur. These built-in exceptions can be viewed using the local() built-in functions as follows :

An exception is an event, which occurs during the execution of a program that disrupts the normal flow of the program’s instructions. In general, when a Python script encounters a situation that it cannot cope with, it raises an exception. An exception is a Python object that represents an error.

When a Python script raises an exception, it must either handle the exception immediately otherwise it terminates and quits.

If you have some suspicious code that may raise an exception, you can defend your program by placing the suspicious code in a try: block. After the try: block, include an except: statement, followed by a block of code which handles the problem as elegantly as possible.

A single try statement can have multiple except statements. This is useful when the try block contains statements that may throw different types of exceptions.

You can also provide a generic except clause, which handles any exception.

After the except clause(s), you can include an else-clause. The code in the else-block executes if the code in the try: block does not raise an exception.

The else-block is a good place for code that does not need the try: block’s protection.
