Python合并字典

1.对于两个字典根据其中的唯一相同键值对进行合并

这里我采用的是两个列表中的字典,并进行合并,将唯一键值相同的字典进行合并

dict1 = [{"names": "80*65*38 天蓝色 ", "pvs": "21433:60656511;1627207:3232484", "skuId": "3212141652714"},
         {"names": "80*65*38 深卡其布色 ", "pvs": "21433:60656511;1627207:3232482", "skuId": "3212141652715"},
         {"names": "80*65*38 粉红色 ", "pvs": "21433:60656511;1627207:3232480", "skuId": "3212141652716"},
         {"names": "80*65*38 紫罗兰 ", "pvs": "21433:60656511;1627207:80882", "skuId": "3212141652717"},
         {"names": "80*65*38 红色 ", "pvs": "21433:60656511;1627207:28326", "skuId": "3212141652718"},
         {"names": "80*65*38 绿色 ", "pvs": "21433:60656511;1627207:28335", "skuId": "3212141652719"},
         {"names": "80*65*38 黄色 ", "pvs": "21433:60656511;1627207:28324", "skuId": "3212141652720"}]

dict2 = [{"priceCent": 398, "price": "3.98", "stock": 49853, "skuId": "3212141652719"},
         {"priceCent": 398, "price": "5.66", "stock": 49738, "skuId": "3212141652720"},
         {"priceCent": 398, "price": "11.78", "stock": 49646, "skuId": "3212141652714"},
         {"priceCent": 398, "price": "45.23", "stock": 49351, "skuId": "3212141652718"},
         {"priceCent": 398, "price": "99", "stock": 49347, "skuId": "3212141652717"},
         {"priceCent": 398, "price": "8.88", "stock": 48503, "skuId": "3212141652715"},
         {"priceCent": 398, "price": "9", "stock": 48853, "skuId": "3212141652716"}]

list1 = []
for dict_1 in dict1:  # 遍历第一个字典
    id1 = dict_1['skuId']  # 获取其中的键值
    name = dict_1['names']
    for dict_2 in dict2:  # 遍历第二个列表
        id2 = dict_2['skuId']
        price = dict_2['price']
        if id1 == id2:  # 根据skuId唯一相同的合并
            dict3 = {'name': name, 'price': price, 'skuId': id2}
            list1.append(dict3)

print(list1)

我用的是淘宝商品合并,合并对应尺寸对应颜色对应价格

2.分割一个列表中,字典键值是相同的到分别两个列表中

list1 = [{"names": "80*65*38 红色 ", "pvs": "21433:60656511;1627207:28326", "skuId": "3212141652718"},
         {"priceCent": 398, "price": "5.66", "stock": 49738, "skuId": "3212141652720"},
         {"names": "80*65*38 绿色 ", "pvs": "21433:60656511;1627207:28335", "skuId": "3212141652719"},
         {"names": "80*65*38 黄色 ", "pvs": "21433:60656511;1627207:28324", "skuId": "3212141652720"},
         {"priceCent": 398, "price": "11.78", "stock": 49646, "skuId": "3212141652714"},
         {"priceCent": 398, "price": "45.23", "stock": 49351, "skuId": "3212141652718"}]
name = []
price = []
for dict1 in list1:
    for k, v in dict1.items():
        if k == 'priceCent':  # 如果字典中的键含有priceCent,放到price列表中
            price.append(dict1)
        elif k == 'names':
            name.append(dict1)
print(name)
print('---------------')
print(price)
