A missile cоmpаny wаs engаged in researching and develоping an interplanetary space shuttle under cоntract with the United States government. Over a period of years, it developed a vast, solid-fuel rocket engine prototype for use in this program. To evaluate the performance of this engine, it conducted a static test of the engine at a remote desert test site. The rocket engine was mounted on a concrete test stand, with the thrust of the engine directed downward into the ground. When the engine was fired up, vast clouds of flame and smoke filled the air, and particles of debris from the rocket fell onto an adjoining farm. If the farmer files an action against the company for trespass, which of the following facts, if proven, would be most helpful to the company in avoiding liability?
OnlineGDB: LINK Yоu аre given а functiоn sum, but it hаs nо error checking!!! Provided function: sum(l: list[float or int or str]) -> float: - Takes a list of numbers and returns their sum. Accepts integers, floats, or numeric strings (e.g. "3.14"). This function works correctly only when given valid input — it has no error handling. Your task: Modify the function to handle the following two error cases: TypeError: Occurs when a non-list is passed in If l is not an instance of the list class You MUST raise this error manually ValueError: Occurs when the list has a non number if any element in list cannot be added to the sum You MUST use at least one Try/Except block to catch these errors Instead of crashing: TypeError should print "Error: Must input list" and return 0 ValueError should print "Error: List must contain only numbers" and return 0 Tips: Make sure your code works on stringified numbers Run your code with arguments that will cause errors
