What are built-in exceptions in Python?

Built-in exceptions in Python are predefined classes that handle errors and exceptional conditions. Examples include ValueError, TypeError, and IndexError.

Can you give me an example of how to use a built-in exception?

Sure! Here's an example:

try:
    number = int(input('Enter a number: '))
except ValueError:
    print('That was not a valid number!')

What happens if I don't handle exceptions?

If you don't handle exceptions, your program may crash or terminate unexpectedly when an error occurs.

Are there any custom exceptions I can create?

Yes, you can create custom exceptions by defining a new class that inherits from the built-in Exception class.
