数组实现分组

 
carts=[{
        "shopping_id": 173744, 
        "product_name": "aaa", 
        "product_code": "TL11111100014",
    },{
        "shopping_id": 173744, 
        "product_name": "aaa", 
        "product_code": "TL11111100018",
    },{
        "shopping_id": 173744, 
        "product_name": "bbb", 
        "product_code": "TL11111100013",
    }]

怎么根据product_name 分组为2组数据
groupcarts=[
{'result':[{},{}]}
,
{'result':[{}]}
]
[解决办法]

groupcarts={};
for x in carts:
    name = x['product_name']
    if name in groupcarts:
        groupcarts[name].append(x)
    else:
        groupcarts[name] = [x]

for x in groupcarts:
    print x, groupcarts[x]

[解决办法]

引用:

Python code
groupcarts={};
for x in carts:
name = x['product_name']
if name in groupcarts:
groupcarts[name].append(x)
else:
groupcarts[name] = [x]

for x in groupcarts:
