작성한 코드 및 에러 메세지

from pymongo import MongoClient
client = MongoClient('mongodb+srv://test:sparta@cluster0.v8bav9j.mongodb.net/Cluster0?retryWrites=true&w=majority')
db = client.dbsparta

db.users.insert_one({'name':'bobby','age':27})
db.users.insert_one({'name':'john','age':23})
db.users.insert_one({'name':'ann','age':20})

Tip 1) </> 아이콘을 눌러 코드박스를 만들어 보세요.

Tip 2) Ctrl+A(맥의 경우 Command+A) 단축키로 코드를 한 번에 선택할 수 있어요!
