python中的操作

#   引入pymongo模塊
import pymongo

讀取數(shù)據(jù)庫

import pandas as pd

def get_key_value(database, collection, key):
    client = pymongo.MongoClient('localhost', 27017)
    db = client['database']
    table = db['collection']
    data = pd.DataFrame(list(table.find()))
    value = data['key']
    return value

保存數(shù)據(jù)至數(shù)據(jù)庫中

def save_to_Mongo(result):
    # 數(shù)據(jù)儲(chǔ)存到mongodb
    try:
        if db[MONGO_TABLE].insert_one(result):
            print('存儲(chǔ)到MongoDB成功', result)
    except Exception:
        print('存儲(chǔ)到MongoDb失敗', result)

MONGO_URl = 'localhost:27017'
MONGO_DB = 'database_name'
client = pymongo.MongoClient(MONGO_URl)
db = client[MONGO_DB]
MONGO_TABLE = 'collection_name'

更新?lián)Q代數(shù)據(jù)庫中數(shù)據(jù)

db[MONGO_TABLE].update_one(
                {'_id': "匹配所需更改的集合"},
                {'$set': {'所需更改的key':'更改的值'}})

將數(shù)據(jù)庫壓縮導(dǎo)出
