写函数，完成以下功能: 
# 例如有:

user_list=[
    {"name": "alex","hobby":"抽烟"}, {"name" :"alex","hobby":"喝酒"}, {"name" :"alex","hobby":"烫头"}, {"name":"wusir","hobby":"喊麦"}, {"name":"wusir","hobby":"街舞"}, ]

# 编写函数处理user_list 并返回如下结果:
# [{"name":"alex","hobby_list": ["抽烟"，"喝酒"，"烫头"]},
# {"name":"wuhir","hobby_list": ["喊麦"，"街舞"]},]

old_dict = dict()
aim_list = [] for a in user_list: k, v = a.values() old_dict.setdefault(k, []).append(v) # old_dict = {'alex': ['抽烟', '喝酒', '烫头'], 'wusir': ['喊麦', '街舞']} for k, v in old_dict.items(): new_dict = dict() new_dict['name'] = k new_dict['hobby'] = v aim_list.append(new_dict) print(aim_list)
