一個數(shù)組里有多個對象，如何根據(jù)對象某個相同屬性，重新組成新數(shù)組，如下圖和代碼

把這個問題向前占個位置，我想知道這個問題的 Python 解決方法。

let result = data.reduce((result, item) => {
    let index = result.findIndex(v => v.shop_id === item.shop_id);
    let {shop_id,shop_name,...single} = item;
    if (index === -1) {
        result.push({shop_id,shop_name,goods_list:[single]});
    } else {
        result[index].goods_list.push(single);
    }
    return result;
}, []);
console.log(result);

    var newData = [];
    data.forEach(function(item) {
        for (var i = 0; i < newData.length; i++) {
            if (newData[i].shop_id === item.shop_id) {
                newData[i].goodsList.push({
                    goods_id: item.goods_id,
                    goods_name: item.goods_name,
                    goods_img: item.goods_img,
                    goods_price: item.goods_price
                })

                return;
            }
        }
        newData.push({
