本文实例讲述了python操作mongodb根据_id查询数据的实现方法。分享给大家供大家参考。具体分析如下:

_id是mongodb自动生成的id,其类型为ObjectId,所以如果需要在python中通过_id查询,就需要转换类型

如果pymongo的版本号小于2.2,使用下面的语句导入ObjectId

from pymongo.objectid import ObjectId
Copy after login

如果pymongo的版本号大于2.2,则使用下面的语句

from bson.objectid import ObjectId
Copy after login

查询代码如下:

collection.find_one({'_id':ObjectId('50f0d76347f4ec148890ef1e')})
Copy after login

希望本文所述对大家的Python程序设计有所帮助。
