python和mongodb交互

1、先安装pymongo库：

pip install pymongo

2、编辑代码文件handel_mongo.py：

import pymongo
from pymongo.collection import Collection


class Connect_mongo(object):
    def __init__(self):
        self.client = pymongo.MongoClient(host='localhost', port=27017)
        self.db_data = self.client['dou_guo_mei_shi']

    def insert_item(self, item):
        db_collection = Collection(self.db_data, 'dou_guo_mei_shi_item')
        db_collection.insert_one(item)


mongo_info = Connect_mongo()

3、在别的文件中使用时，直接导入：

 from handel_mongo import mongo_info
