數組，列表，list對相同數據進行重新排序

列表返回數據如下

[
{"shop":"小米","name":"小米3"},
{"shop":"小米","name":"小米5"},
{"shop":"小米","name":"小米6"},
{"shop":"華爲","name":"華爲榮耀10"},
{"shop":"小米","name":"小米mix"}
]

要將這個列表按照shop來排數組，理想的數據格式如下

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

使用groupby函數對數據重組
