1、我是初學(xué)者，自學(xué)點點滴滴，目前遇到個問題，mongodb數(shù)據(jù)庫有這些的數(shù)據(jù)，其中huifuzhuagntai的0是未回復(fù)的意思，1是已回復(fù)的意思{id:1,huifuzhuangtai:0,title:標(biāo)題}{id:1,huifuzhuangtai:1,title:標(biāo)題}{id:1,huifuzhuangtai:1,title:標(biāo)題}{id:1,huifuzhuangtai:1,title:標(biāo)題}{id:1,huifuzhuangtai:1,title:標(biāo)題}{id:1,huifuzhuangtai:1,title:標(biāo)題}
2、我用管道篩選的數(shù)據(jù)，
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()
得到的結(jié)果是
{'name': 1, 'counts': 5}{'name': 0, 'counts': 1}
我想得到的結(jié)果是{'已回復(fù)': 1, 'counts': 5}{'未回復(fù)': 0, 'counts': 1}這個怎么弄，請求大俠幫忙看看，小白太笨了
