我正在做一个网络应用程序,我有一个疑问。我需要获得MongoDb JSON的值吗?宾语。我发布了我的代码..
import pymongo
try:
conn =pymongo.MongoClient('localhost')
print('Conexion realizada:')
except pymongo.errors.ConnectionFailure, e:
print('No se ha podido realizar la conexion: %s' % e)
db = conn.test
coll = db.puntos
print(list(coll.oxigeno.find())) <-- I want to print the Oxigeno value of the Objct
非常感谢你
答案 0 :(得分:0)
当您说要打印对象的Oxigeno值时,不确定您想要什么,但是要在查询结果中打印文件的oxigeno值,请执行
for doc in coll.find(): # .find() returns cursor which is meant for iteration
print(doc["oxigeno"]) # doc is a python dictionary representing the returned BSON document
