Which class serves as the base for all non-system-exiting exceptions in Python?

• A. BaseException
• B. SystemExit
• C. Exception
• D. RuntimeError

Answer: (C)

The class that serves as the base for all non-system-exiting exceptions in Python is the Exception class. This is a fundamental aspect of Python's error handling framework, as it defines the general behavior of exceptions that are raised during program execution. When an error occurs in a Python program—such as an invalid operation or a failed condition—an instance of the Exception class or its subclasses is created and raised, allowing the program to handle the error gracefully. This mechanism provides a structured way to catch and deal with unexpected situations through try-except blocks. Although BaseException is the parent class of all exceptions, it is generally used for system-exiting exceptions, such as SystemExit, KeyboardInterrupt, and GeneratorExit. Thus, while it encompasses all exceptions, the Exception class is specifically designated for most user-defined exceptions and the errors that programs are likely to encounter, making it the standard for handling typical exception scenarios. In summary, the Exception class is essential for managing errors in user-level code, while BaseException includes all types of exceptions, including those not meant for general program flow control.
