# 安装 pymongo pip install pymongo

import pymongo

try:

    # 1.链接mongod的服务

    mongo_py = pymongo.MongoClient()

    # 2.库和表的名字; 有数据会自动建库建表

    # 数据库

    # db = mongo_py['six']

    # 表 集合

    # collection = db['stu']

    # collection = mongo_py['six']['stu']

    collection = mongo_py.six.stu

    # 3.插入数据

    one = {"name": "张三", "age": 50}

    two_many = [

        {"name": "小三", "age": 50},

        {"name": "李四", "age": 30},

        {"name": "王五", "age": 20},

        {"name": "小刘", "age": 15}

    # collection.insert_one(one)

    # collection.insert_many(two_many)

    # collection.insert()

    # 删除数据

    # collection.delete_one({"age": 15})

    # collection.delete_many({"age": 50})

    # 修改数据

    #查询

    result = collection.find({"age":100})

    result = collection.find_one({'age':100})
