Exception Handling in Python

In Python, the try and except blocks are used for exception handling. Exception handling allows you to gracefully handle errors and exceptions that may occur during the execution of your code. This is important because it prevents your program from crashing when it encounters unexpected issues.

• try block encloses the code that may raise an exception.
• catch block if exception raises in try block, control jumps to catch block.
• else block if no exception raises in try block, else block is executed.
• finally block will be executed all the time whether exception occurs or not.

Catching Exceptions

You can also determine the type of error in exception handling. This is called generic exception handling.

Handling Multiple Exceptions

Handling multiple exceptions in Python involves using multiple except blocks, each handling a specific type of exception.

Else Block

We can add an else block after catch block. It will be executed when no exception occurs.

Finally Block

We can add an finally block at the end. It will always be executed.
