使用PyMongo将字符串转换成objectid，根据官方文档，但是提示错误
http://api.mongodb.org/python/1.7/api...

from pymongo.objectid import ObjectId

key='507f1f77bcf86cd799439011'
ObjectId(key)

错误消息
ImportError: No module named objectid

Answer 1

import bson.objectid
# 或者
from bson import objectid

>>> from bson.objectid import ObjectId
>>> ObjectId('507f1f77bcf86cd799439011')
ObjectId('507f1f77bcf86cd799439011')
