Alas, deep copying also doesn’t work as expected with DataFile objects, but for other reasons. The error message suggests that Python did try to recursively duplicate the file handle, but failed due to lack of support for such objects. Note: Python’s field-for-field copying shares some si...

Python def process(context, input_value): if input_value is not None: expensive_computation(context, input_value) else: logging.info("skipping expensive: %s", input_value) In this example, expensive_computation() runs code that takes a long time, such as multiplying big arrays of numbers...
