python连接mongodb

1.安装pymongo

2.连接测试

#!/usr/bin/env python
# coding=utf-8

from pymongo import MongoClient
from datetime import datetime

#链接数据库的客户端
client = MongoClient('localhost', 27017)
# 选择数据库
db = client.test
# 选择集合
collection = db.blog

collection.insert({'title': 'python connect mongo', "content": "beautiful", "date": datetime.now()})
for obj in collection.find():
    print (obj)
# collection.update({name: "xxx"}, {name: "XXX", args:...}) 第一个参数找到要要更新的文档， 后面是要更新的数据
# collection.remove()删除集合中的全部数据，但是集合依然存在，索引也在
# collection.drop()删除集合collection

3.测试结果
