python使用Pymongo调用mongodb.请问 如何生成ObjectId？
引用from bson import ObjectId就可以啦。
from bson import ObjectId
如：
#encoding:utf-8import pymongofrom bson import ObjectIddbconnection=pymongo.Connection('localhost',27017)db = dbconnection.testcoll = db.userd=coll.find_one({'_id':ObjectId('577d211b1d41c8303f73cf7d')})
#encoding:utf-8
import pymongo
dbconnection=pymongo.Connection('localhost',27017)
db = dbconnection.test
coll = db.user
d=coll.find_one({'_id':ObjectId('577d211b1d41c8303f73cf7d')})
