将list3 这种数据类型转化成list4类型,你写的代码必须支持可拓展

list3 = [
    {"name": "alex", "hobby": "抽烟"},
    {"name": "alex", "hobby": "喝酒"},
    {"name": "alex", "hobby": "烫头"},
    {"name": "alex", "hobby": "Massage"},
    {"name": "wusir", "hobby": "喊麦"},
    {"name": "wusir", "hobby": "街舞"},]
list4 = [
    {"name": "alex", "hobby_list": ["抽烟", "喝酒", "烫头", "Massage"]},
    {"name": "wusir", "hobby_list": ["喊麦", "街舞"]},]

list4= []
for ren in list3:
    for el in list4:
        if el['name'] == ren['name']:
            el['hobby_list'].append(ren['hobby'])
            break
    else:
        dic = {}
        dic['name'] = ren['name']
        dic['hobby_list'] = [ren['hobby']]
        list4.append(dic)
print(list4)

重点在于新名字的加入用新字典直接暴力添加相同数据然后在加入列表
