数组，列表，list对相同数据进行重新排序

列表返回数据如下

[
{"shop":"小米","name":"小米3"},
{"shop":"小米","name":"小米5"},
{"shop":"小米","name":"小米6"},
{"shop":"华为","name":"华为荣耀10"},
{"shop":"小米","name":"小米mix"}
]

要将这个列表按照shop来排数组，理想的数据格式如下

[
{"shop":"小米","list":[
{name:"小米9"},
{name:""小米10}
]},
{"shop":"华为","list":[
{name:"华为p20"},
{name:"华为p30"}
]}
]

使用groupby函数对数据重组
