What happens when you raise an exception in a function?

• A. The function terminates immediately
• B. Control is passed to the calling function
• C. It returns an error code
• D. It gets logged without raising

Answer: (B)

When an exception is raised in a function, control is passed to the calling function. This means that the Python interpreter stops executing the current function and begins to look for an exception handler in the places that called this function. If an appropriate handler is found in the calling function, the program resumes execution there; if not, the exception continues to propagate up the call stack until it is either handled or reaches the top level of execution, resulting in program termination and printing a traceback. This behavior allows for a structured way to handle errors, enabling developers to manage exceptions more effectively rather than just stopping the program. Raising an exception serves as a way to signal that an error or unexpected condition has occurred, and by handling that exception somewhere in the call stack, the program can continue running or can exit gracefully by implementing specific error responses as needed.
