제목 그대로 궁금한데요. Something::_init이 Something 클래스 안에있는 init클래스까지는 이해가 됩니다. 그런데 왜 _init 옆에 또 Something을 써줘야하나요??

2분 41초에go(3,3) go(4,4)가 어떻게 나오는지 알수있을까요??go(3,4)에서 min = (3+4)/2 = 3.5이렇게 3.5가 나오는데 ... mid가 int값이면 반올림해야되는건가요? 아니면 소수 점은 버리는건가요?? 이해가 잘 안갑니다 ㅠㅠ

MemberRepositoryV1에 있는 delete는 없는 테이블을 삭제해도 왜 문제가 없는건가요? accountTransfer() 테스트 부분에서 리포지토리에 memberA,memberB만 저장했을때 aftereach에서는 memberEx까지 삭제해주는데 왜 예외가 발생하지 않는건지 궁금합니다

testing 자리에 조건과 조건을 ,로 연결하면 안되는 게 맞는지 질문드립니다ㅠㅠVisual studio에서 해보니까 testing 자리에 조건 둘을 ,로 쓰면 왼쪽 조건은 무시된다고 나오는데 이게 모든 경우에 그런건지 특정 경우에 한정된 건지 궁금합니다.

강사님 안녕하세요!강사님 수업 들으면서 나날이 네트워크 지식이 깊어지고 있어 감사할 뿐입니다.제가 Transport 계층 개념 추가 강의를 듣다가 UDP 통신에 관해 의문이 생겨서 질문 남깁니다.우선 강의에서 위 그림을 잘못된 것이라 하셨습니다.저기서 밑에 Response는 다 지워야 되는 게 맞는거라 하셨는데 여기에 의문이 있습니다.실시간 통신에서 UDP 방식을 쓴다 하셨는데 예를 들어 저희가 네이버에서 실시간축구 중계를 보기 위해 "중계 시청" 버튼을 클릭하면 그게 Client가 Server에게"축구 보게 데이터 좀 "라고 Request 요청을 보내는 거라 생각합니다. 그럼 서버가 요청을받아 클라이언트에게 축구 중계 데이터를 일방적으로 계속 빠르게 데이터를 주는 게밑의 Response 화살표라고 생각합니다.제가 생각하는 부분에 있어서 기술적으로나 논리적으로 틀린 게 있을까요?

링크를 복사하면 흰화면만 보이는데 이 경우에는 어떻게 해야하나요?

왜 nLogN 인지 이해가 안되는데 조금만 더 쉽게 설명 좀 부탁드립니다.그리고 중간 설명에서 log2의 n은 무엇을 말하는건가요?

import requests from bs4 import BeautifulSoup respones = requests.get("https://www.coupang.com/np/categories/498917") html = respones.text soup = BeautifulSoup(html,'html.parser') item = soup.select(".baby-product-link") # 쿠팡 아이템 1페이지 모두 지정 for items in item: print(f"{pn}페이지 입니다=========================") name = items.select("div.name") #리스트 url = items.attrs['href'] #두번째 링크의 href를 추출 그리고 url에 저장 response = requests.get(url, headers={'user-agent' : 'mozila/5.0'}) # headers={'user-agent' : 'mozila/5.0'}로 기계같이 보이는 오류를 막음 #받아온 url들을 다시 불러옴 html = response.text # 받아온걸 텍스트로 변환 soup = BeautifulSoup(html,'html.parser') # 알아보기쉽게 만들어줌 img = soup.attrs[".src"]# 본문이 가지고 있는 자신만의 태그로 지정 print (name,img) pn = pn + 1이런식으로 응용 해보았는데 실행을 하면 오류도 없고 아무 동작이 없네요 .. 이런 경우 어떻게 해야하죠 ? 터미널에는 아무 글도 안떠요 그냥 파일 경로만 뜹니다

먼저 양질의 퀄리티 강의를 제공해주신 교수님께 감사의 말씀을 드립니다.그런데, 어떤 강의에서는 동영상에서 소스코드를 왔다갔다 움직이셔서 보고 따라 치기가 힘들더라구요. 혹시 "홍정모 공식 카페"에 따배씨++에 관한 소스코드가 제공되어 있을까요?? 그렇지 않다면, 어디서 리소스를 얻을 수 있을까요? 감사합니다 :)

경로를 확실히 주었는데 vs code에서는 작동하지만 intellij 에서는 적용되지 않습니다.다른 방법은 없을까요?

안녕하세요 캡틴 판교님 제가 강의를 따라서 진행을 하던중 오류를 만나서 해결이 안되서 질문 드립니다. 뭐가 문제일까요? 

 저의 풀이입니다 . 강의에서sum == total // 2이 코드에서 예외가 발생할 수 있다고 하셨는데 몫을 구하지말고바로 나누기로 해서 풀면 되지않을까요? 그리고 궁금한점이파이썬에서는 타입이 달라도 ( 16 정수타입 과 16.0 실수타입 )같다고 인식되나요?
