Question about ds to universal

def _merge_zero_shards(param_base_path, state, tp_degree, slice_shape):
    slices = []
    for tp_index in range(tp_degree):
        prefix_path = os.path.join(param_base_path, str(tp_index), f"{state}")
        paths = sorted(list(glob.glob(f"{prefix_path}.0*")))
        #print(paths)
        shards = [torch.load(p) for p in paths]
        slice = torch.cat(shards, dim=0).reshape(slice_shape)
        slices.append(slice)

    return slices

hello，what does f"{prefix_path}.0*" mean? what if the path startswith f"{prefix_path}.1*"?
