Python 连接mongodb

新建配置文件 config.ini

[db]
DB_USER = test_db
DB_PASSWORD = XXX6778a

新建配置文件 mongo_config.ini

import configparser


def getConfig(dbkey):
    Config = configparser.ConfigParser()
    Config.read("config.ini")
    value = Config.get("db", dbkey)
    return value;

新建demo.py

from pymongo import MongoClient
import mongo_config

#连接MongoDB数据库
DB_USER=mongo_config.getConfig('DB_USER')
DB_PASSWORD=mongo_config.getConfig('DB_PASSWORD')

client = MongoClient('10.18.12.209', 27018)
db = client.matrix_db
db.authenticate(DB_USER, DB_PASSWORD)
myset = db.neo.thirdparty.account.AccountEntity

for item in myset.find():
    print(item)

最开始遇到报错：ModuleNotFoundError: No module named 'pymongo'
