小编mus*_*afa的帖子

例如，我有这个字典数组

 [["Country":"Egypt","Name":"Mustafa","Age":"20"],["Country":"Palestine","Name":"Omar","Age":"15"],["Country":"Egypt","Name":"Ali","Age":"40"],["Country":"Jordan","Name":"Ahmad","Age":"25"],["Country":"Palestine","Name":"Amani","Age":"30"],["Country":"Jordan","Name":"Mustafa","Age":"20"]]

我想按国家对它们进行分组，以成为

  {"Egypt": [{"Country":"Egypt","Name":"Mustafa","Age":"20"} {"Country":"Egypt","Name":"Ali","Age":"40"}],
   "Palestine": [{"Country":"Palestine","Name":"Amani","Age":"30"},{"Country":"Palestine","Name":"Omar","Age":"15"}],
   "Jordan":[{"Country":"Jordan","Name":"Ahmad","Age":"25"},{"Country":"Jordan","Name":"Mustafa","Age":"20"}]
}

请帮忙。
