Zip Longest Function Implementation

The function utilizes the zip_longest function from the itertools library to retrieve elements from the longest iterator. If other iterators are shorter, it fills them with fillvalue.

def zip_longest(*args, fillvalue=None):
    """
    从最长的迭代器中获取元素，较短的迭代器用fillvalue填充。
    """
    # 使用zip_longest从itertools库中获取长序列的元素
    from itertools import zip_longest
    for item in zip_longest(*args, fillvalue=fillvalue):
        yield item
