안녕하세요 db랑 파이썬 연결이 안돼서 문의드립니다. 여러차례 실행했는데 뭐가 문제인지 못 찾겠어요 감사합니다 ㅠㅠ

(작성한 코드)

from pymongo import MongoClient
client = MongoClient('mongodb+srv://test:sparta@cluster0.eezm7a8.mongodb.net/Cluster0?retryWrites=true&w=majority')
db = client.dbsparta

doc = {
    'name':'bob',
    'age':27
}

db.users.insert_one(doc)

(에러 메세지)

Traceback (most recent call last):
