字典输出生成如何进行改名

Question

1、我是初学者，自学点点滴滴，目前遇到个问题，mongodb数据库有这些的数据，其中huifuzhuagntai的0是未回复的意思，1是已回复的意思{id:1,huifuzhuangtai:0,title:标题}{id:1,huifuzhuangtai:1,title:标题}{id:1,huifuzhuangtai:1,title:标题}{id:1,huifuzhuangtai:1,title:标题}{id:1,huifuzhuangtai:1,title:标题}{id:1,huifuzhuangtai:1,title:标题} 2、我用管道筛选的数据， def zong2(): pipeline=[ {'$group':{'_id':'$huifuzhuangtai','counts':{'$sum':1}}} ] for i in item_info.aggregate(pipeline): data={ 'name':i['_id'], 'counts':i['counts'] } print(data) zong2() 得到的结果是 {'name': 1, 'counts': 5}{'name': 0, 'counts': 1} 我想得到的结果是{'已回复': 1, 'counts': 5}{'未回复': 0, 'counts': 1}这个怎么弄，请求大侠帮忙看看，小白太笨了

Answer 1

def zong2():
    pipeline=[
        {'$group':{'_id':'$huifuzhuangtai','counts':{'$sum':1}}}
    ]
    for i in item_info.aggregate(pipeline):
        data={('未回复','已回复')[i['_id']]:i['counts']}
        print(data)
zong2()

或者

data={
    ('未回复','已回复')[i['_id']]:i['_id'],
    'counts':i['counts']
}
