数组实现分组

Python code

 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]

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:    print x, groupcarts[x]
