In Python, exception handling is done using the try, except, else, and finally blocks to manage errors gracefully without crashing the program.

How It Works:

• The try block contains code that might raise an exception.

• If an exception occurs, Python jumps to the matching except block.

• If no exception occurs, the else block (if present) runs.

• The finally block (if present) runs regardless of whether an exception occurred, often used for cleanup (like closing files or releasing resources).

Catching Multiple Exceptions:

You can handle multiple exception types separately or together:

Custom Exceptions:

You can define your own exceptions by subclassing Exception.

Summary:

• Use try-except to catch errors and keep your program running.

• Use else for code that should run only if no errors occur.

• Use finally for cleanup actions that must happen regardless of errors.
