3-12 강의 보면서 다시 시도하고 있는데 계속 같은 오류가 뜹니다 ㅠㅠ

from pymongo import MongoClient
client = MongoClient('mongodb+srv://test:sparta@cluster0.n4hae8m.mongodb.net/Cluster0?retryWrites=true&w=majority')
db = client.dbsparta

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

db.users.insert_one(doc)

위의 코드를 입력하고 실행하면 아래의 오류가 나옵니다.. 드라이버 : 파이썬, 버전 : 3.6으로 올바르게 선택했는데도 그러네요
