python中list中的元素为字典,对字典中value相同的进行分组

hosts_nodes为一个list中的元素为字典
def match_rac_disks(hosts_nodes):
    result = list()
    select_checked = list()
    for j in hosts_nodes:
        for k in j['branch']:
            if 'checked' in k:
                k['map_disk_lab'] = j['label']
                k['host_ident'] = j['id']
                select_checked.append(k)
    for i in range(len(select_checked)):
        if len(select_checked) != 0:
            tmp = list()
            tmp2 = list()
            tmp.append(select_checked[0])
            tmp2.append(0)
            for j in range(1, len(select_checked)):
                if select_checked[0]['id'] == select_checked[j]['id']:
                    tmp.append(select_checked[j])
                    tmp2.append(j)
            result.append(tmp)
            for index, s in enumerate(tmp2):
                del select_checked[s - index]
        else:
            break
    return result
