카카오맵 연결 에러

강의명: 카카오맵 API를 활용해서 지도를 넣는 방법

Q. Error 사항

GET file://dapi.kakao.com/v2/maps/sdk.js?appkey=8ca2656741c19be97bc5b5c408a37b73 net::ERR_FILE_NOT_FOUND
script.js:3 Uncaught ReferenceError: kakao is not defined
at script.js:3:14

Q 질문사항

왜 카카오맵 지도가 나오질 않을까요?
Url 이 문제인거 같은데..
제 html 화면은
file:///C:/%EA%B9%80%EC%9E%AC%EB%AA%85/%5BAIDX%5D%20python/%5Bcode%5D/221128_index.html
이렇게 나옵니다.
http://127.0.0.1:5500 이렇게 나오질 않네요.. 왜그럴까요 ㅠㅠ

<html> 코드 / (script.js)는 그대로 따왔어요
