需要安裝mongo庫，安裝命令如下（ubuntu）：pip install pymongo

使用python操作MongoDB

from pymongo import mongoclient connect mongoclient host 127.0.0.1 port 27017 連線到資料庫主機 返回乙個連線 mongoclient host 127.0.0.1 27017 document class dict,tz ...

python對MongoDB的操作

python連線 try conn mongoclient ip,port database conn db db為資料庫名稱 my set database tb tb為表名稱 logger.info 需要檢測的字段 format field nm all my set.estimated doc...
