This function is used to merge multiple iterable objects into a single iterator. If one of the iterable objects is exhausted, fillvalue is used to fill the remaining positions.

def zip_longest(*iterables, fillvalue=None):
    # 将多个可迭代对象合并为一个新的迭代器，如果其中一个可迭代对象被耗尽，则用fillvalue填充
    from itertools import zip_longest as it_zip_longest

    def wrapper(*iterables, fillvalue=None):
        return it_zip_longest(*iterables, fillvalue=fillvalue)
