maths.allocation_number ======================= .. py:module:: maths.allocation_number .. autoapi-nested-parse:: In a multi-threaded download, this algorithm could be used to provide each worker thread with a block of non-overlapping bytes to download. For example: for i in allocation_list: requests.get(url,headers={'Range':f'bytes={i}'}) Functions --------- .. autoapisummary:: maths.allocation_number.allocation_num Module Contents --------------- .. py:function:: allocation_num(number_of_bytes: int, partitions: int) -> list[str] Divide a number of bytes into x partitions. :param number_of_bytes: the total of bytes. :param partitions: the number of partition need to be allocated. :return: list of bytes to be assigned to each worker thread >>> allocation_num(16647, 4) ['1-4161', '4162-8322', '8323-12483', '12484-16647'] >>> allocation_num(50000, 5) ['1-10000', '10001-20000', '20001-30000', '30001-40000', '40001-50000'] >>> allocation_num(888, 999) Traceback (most recent call last): ...
