05:00 쯤에 한번에 선택하는거 어떻게 하신건가요.. ?

이렇게 못알아먹는데 어캐해야하나요 ;ㅅ;

import random import os import sys def input_check(msg, casting=int):     while True:         try:             user_input = int(input("몇 일까요?(1 ~ 99 사이의 정수만 입력하세요) : "))             if user_input == "n":                 sys.exit()             return user_input         except:             continue chance = 10 os.system("cls") print("1부터 99까지의 숫자를 10번의 시도 안에 맞춰보는 게임입니다") def game():     global count     count = 0     number = random.randint(1, 99)     while count < chance:         count += 1         user_input = input_check("몇 일까요?(1 ~ 99 사이의 정수만 입력하세요) : ")         if user_input == number:              print("성공! {}이(가) 맞습니다.".format(number))             print("{}번만에 성공하셨습니다.".format(count))             break         elif count == chance:             print("실패, 정답은 {}입니다.".format(number))             break         elif user_input < number:             print("{}보다 큽니다.".format(user_input))         elif user_input > number:             print("{}보다 작습니다.".format(user_input))                  game() while True:     print("게임을 계속 하시겠습니까?(Y/N) : ", end='')     answer = input()     if answer == "y" or answer == "Y":         game()     elif answer == "n" or answer == "N":         print("게임을 종료합니다.")         break 위 코드는 제가 일부 기능을 추가 한 상태입니다. 그런데 숫자를 입력 받을 때 사용자가 n을 입력하면 게임이 종료되게끔 이런 저런 시도를 해봤는데 안되더라고요 그래서  user_input = input("몇 일까요?(1 ~ 99 사이의 정수만 입력하세요) : ") if user_input == "n": sys.exit() 마지막으로 input_check 안에 이런식으로 해봤는데도 의도대로 안되더라고요. 무엇이 문제인지 잘 모르겠습니다. 어떻게 하면 n을 입력받았을 때 프로그램이 종료될까요? 아주 단순한 문제인거 같은데 답을 모르겠습니다.

생활코딩 node부분다하고 이제 다시시작하고있어서 좀늦엇네요! 잘지내고계시죠^^ㅎㅎ 일단 로그인까지는 토큰잘생성되있고 , 로그인도됩니다. 그후, 미들웨어추가하고 오늘 로그아웃까지해서 실행시키니까  자꾸 이런에러가 떠서요... 이유를 모르겠습니다 . user 객체를 가져올수없다? 그래서 require 부분확인했는데 똑같고그래서요... 오타인가싶어서 존안님 깃허브 코드를 가져와서사용했는데도 똑같이떠서요..

기선님의 jpa 강의를 듣고 jpa 를 활용해보기 위한 연습용 프로젝트를 진행하고 있는 중입니다. DB에 데이터가 들어가 있는 상태에서 스프링 데이터 jpa 의 findById() 메소드를 활용해 select 쿼리를 보내봤습니다. 그런데 이상하게도 값이 받아와지지 않아 두번 연속 요청을 보냈더니 그 다음부터는 값을 받아오는데 이게 가능한 일인지 궁금해서 여쭤봅니다 ..  기본적으로 이런 일은 발생하지 않는게 맞고 어디선가 제가 코드를 잘못 작성해놓은거겠죠..?  orderDetailRepository 에 findById() 를 재정의 하거나 다른 메서드를 구현해놓지도 않은 상태입니다 .

function add (x:string,y:string):string; function add (x:number,y:number):number; function add (x:number|string,y:number|string):number|string { if (typeof x === 'number' && typeof y === 'number') { return x+y; } else { let result = Number(x) + Number(y); return result; } } const v1:number = add(10,20); const v2:string = add('1','2'); const v3 = add(1,'10'); 강의 잘 보고 있습니다! 1.v3에서 Number('10')을 했을 때 NaN이 나오고 따라서 리턴값이 NaN이지만, typeof NaN === number로 알고 있고 리턴값 타입 때문에 오류가 뜨는 것 아닌 것 같은데 어떤 부분에서 오류가 뜨는지 더 자세히 알 수 있을까요? 2.그리고 v3값은 3번째로 정의한 function add(x,y)를 따라 실행된다 보면 될까요?

2장에서 타이타닉 예제를 공부할 때 만들었던 함수가 3장에서 그대로 이용가능하다는 것은 이 함수가 전역함수인건가요...?ㅠㅠ 

위와 같은 오류가 계속 발생합니다. pip install --upgrade pip을 해도 비슷한 오류가 나오네요

안녕하세요. 강의 너무 잘 듣고 있습니다. 이해가 잘 되도록 설명을 정말 잘해주셔서 재밌게 공부하고 있습니다. 강의를 듣던 중 의문이 생겨 질문드립니다. member의 아이디가 1로 출력됩니다. MySQL을 사용할 때(Oracle로 시퀀스를 만들어도 동일합니다.) persist를 호출하는 시점에서 memebr가 id로 1로 초기화가 되는데 내부적으로 setter를 호출해서 초기화되는 것이라고 생각했었습니다. 근데 setter를 지워도 초기화가 되는 것이 신기합니다. private 제어자로 설정했기 때문에 member.id = 1; 이렇게 할 수 도 없을텐데 어떤 과정으로 초기화가 되는건지 궁금합니다.

영한님 안녕하세요. Spring Data JPA 로 리파지토리를 만들고 테스트하다가 나온 사항에 대해 궁금증이 있어 문의를 드립니다. 질문사항은 다음과 같습니다. ㅇ 목적: 여러 개의 row를 한 번에 insert할 때의 성능을 최적화하려고 함 (여러 개의 row를 넣는 테이블의 pk는 직접 입력을 받아 넣는 id 형식입니다.) ㅇ 구현 의도: multi-value insert (insert into table values(...), (...), ... , (...) ) ㅇ 시도 -  JpaRepository의 saveAll() 메서드를 사용 (MySQL의 경우 multi-value insert 시 jdbc 옵션으로 rewriteBatchedStatements=true를, PostgreSQL의 경우 reWriteBatchedInserts=true를 주면 되는 것으로 알고 있습니다. h2 DB는 그런 것이 있는지 모르겠네요. 일단 format_sql=true로 했을 때 남겨진 로그로는 해당 내역을 확인하기 힘들었습니다.)  - saveAll() 시 isNew 필드를 통해 persist, merge 분기를 타기 때문에 성능에 이슈가 있을 것으로 보고, 부가적인 select문 실행을 막기 위해 isNew 필드값을 아래와 같이 true로 만들었습니다. @Transientprivate boolean isNew = true;@Overridepublic ClassId getId() { return ClassId.builder() .pk1(pk1) .pk2(pk2) .pk3(pk3) .pk4(pk4) .pk5(pk5) .build();}@Overridepublic boolean isNew() { return true;}@PrePersist@PostLoadpublic void markNotNew(){ isNew = false;} - bulk insert를 위한 batch_size 등의 옵션 추가 (추가한 옵션은 spring.jpa.properties 하위입니다.) jdbc: batch_size: 1000 batch_versioned_data: trueorder_inserts: trueorder_updates: true ㅇ 의문점 1. 일단, 찍히는 sql이 insert into table values(...), (...), ... , (...)  과 같이 찍히지 않습니다. 과연 bulk로 모아서 실행이 되는 것인지가 궁금합니다. 물론 batch_size가 0일때보다 200일 때의 성능 개선이 있긴 한데 약간 미미하다는 생각이 들어서요... 2. em.persist를 n 번 수행한 뒤 flush한 결과보다 성능이 못한데, 이것이 무엇 때문에 나오는 결과인지 궁금합니다. (SimpleJpaRepository.class를 보니 saveAll 함수 내부 로직에서 save를 n 번 호출하고 save 함수 내에서 isNew를 체크하는데 여기서 오는 차이인지..) 3. 원래 100000 정도의 데이터를 insert 할 시에 이 정도의 성능이 나오는 것인지 궁금합니다. (테스트 결과는 아래에 있습니다.) 4. batch_size마다 saveAll()를 해 주고 리스트를 초기화 시켜주는 것이 성능상으로 의미가 있을 지 궁금합니다. (아래 성능 테스트에서는 리스트에 꽉 채운 뒤에 마지막에 saveAll을 호출했었습니다. 궁금하여 batch_size마다 saveAll을 호출하고 리스트를 초기화 시켰보았지만 시간 차이가 거의 나지 않았습니다. 제가 테스트를 잘못한 것인지...)참고 링크: https://persistencelayer.wixsite.com/springboot-hibernate/post/the-best-way-to-batch-inserts-via-saveall-iterable-s-entities 성능 테스트 data size = 100000 1. batch_size = 0 em.persist 사용: 6807 ms JpaRepository.saveAll() 사용: 7861 ms 2. batch_size = 200 em.persist 사용: 5547 ms JpaRepository.saveAll() 사용: 7187 ms 3. batch_size = 500 em.persist 사용: 5452 ms JpaRepository.saveAll() 사용: 6489 ms 4. batch_size = 1000 em.persist 사용: 5684 ms (배치 사이즈가 증가했음에도 더 오래 걸림) JpaRepository.saveAll() 사용: 6360 ms 5. batch_size = 5000 em.persist 사용: 5815 ms (배치 사이즈가 증가했음에도 더 오래 걸림) JpaRepository.saveAll() 사용: 6659 ms (배치 사이즈가 증가했음에도 더 오래 걸림) 보통 영한님은 여러 row를 한 번에 insert하려고 할 때 어떻게 구현을 하시는지 궁금합니다. 답변 부탁드리겠습니다. 긴 내용 읽어주셔서 감사합니다 :)

정리 1. 1. fn 은 글로벌 오브젝트에 바인딩되고 fn( ) 호출시  대상 오브젝트가 없는 상태로 호출된다. 2. 실제 코드인 book.get( )  호출 → this 는 widnow 를 참조 한다. 3. var value = 456 은 get 메소드 의 지역변수로 할당 4. this === window 는 true 5. this.value 는 window 에서 value 를 찾지만 존재하지 않기 때문에 undefined 정리 2. 1. book( ) 을 호출 → 오브젝트가 없기 때문에 this 는 window 를 참조 2. this.getTitle( ) 호출시 window.getTitle( ) 와 동일하기 때문에 → HTML 책 출력 3. getTitle( ) 호출시 현재의 실행 영역에서 선언적 환경 레코드 있는 function getTitle( ) 를 먼저 호출 → JS책 출력

문제를 찾아보다가 https://www.inflearn.com/questions/17219 문의 글을 봤습니다. 현재 영한님 예시 코드와 똑같이 pom.xml에서 hibernate는 5.3.10.Final, h2database는 1.4.199버젼을 사용하고 있습니다. hibernate.hbm2ddl.auto의 value = "create" 상태인데, 테이블들이 제약조건이 꼬여서 그런지 삭제가 되질 않습니다ㅠ (ex1-hello-jpa 프로젝트와 jpashop 프로젝트 모두 그렇습니다) 예시 코드를 메일로 송부드릴테니 한번 봐주시면 감사드리겠습니다ㅠㅠ 아래는 에러 포함 출력 결과입니다.

안녕하세요 wordcloud(fac)를 하면 fac가 아닌 gym 데이터가 출력이 되서 kernel  Restart&Run All 해봤는데도   gym이 출력이 되는데 왜이럴까요? 

안녕하세요 유익한 강의 제공에 감사드립니다. 강의를 보고 실무에 적용하려고 진행 중 어려운 부분이 있어 질문드립니다. 엑셀에 있는 자료를 읽어서 인터넷에서 검색후 검색 결과를 다시 해당 엑셀파일에 저장하는 작업을 하려고 로봇을 만들었습니다. 이렇게 한건 처리하는건 제공해주신 강의를 통해서 만드는데 성공하였습니다.  그런데 이 작업을 여러번 반복 시키려고 하는데요 예를 들어 엑셀에 A1셀부터 A5셀에 있는 데이타를 순차적으로 읽어서 인터넷 검색 후 해당 검색결과를 B1셀부터 B5셀까지 자동으로 저장하도록 하려면 어떤 액티비티를 써야 할지 조언 부탁드립니다. 현재는 아래 순으로 작업을 하였습니다. 엑셀APP.스코프-리드레인지-오픈브라우저-클릭-타입인투 인풋-데이타스크랩핑- 라이트레인지

python run.py로 재시작하고 웹사이트를 새로고침하면 남박사님은 로그인 정보가 없어지고 로그아웃되는 것 같은데요. 저는 안되네요!! 원래 그럴수도 있는걸까요??? @ app.route("/login", methods=["GET", "POST"]) def member_login(): if request.method == "POST": email = request.form.get("email") password = request.form.get("pass") next_url = request.form.get("next_url") members = mongo.db.members data = members.find_one({"email": email}) if data is None: flash("회원 정보가 없습니다.") return redirect(url_for("member_login")) else: if data.get("pass") == password: session["email"] = email session["name"] = data.get("name") session["id"] = str(data.get("_id")) session.permanent = True if next_url is not None: return redirect(next_url) else: return redirect(url_for("lists")) return redirect(url_for("lists")) else: flash("비밀번호가 일치하지 않습니다.") return redirect(url_for("member_login")) return "" else: next_url = request.args.get("next_url", type=str) if next_url is not None: return render_template("login.html", next_url=next_url) else: return render_template("login.html")

질문은 아니고 렌더링이 두번씩되어서 funcId가 강의 영상과 다르게 출력되더라구요. Index.js에 StrictMode를 제거하면서 해결했습니다.

package.json 파일과 index.js 파일까지 강의대로 수정 마친 후 터미널에서 npm run start 입력하니 에러가 뜨는데 무슨 문제일까요?

messages가 복수개이고 [-1]을 통해서 가장 마지막 메시지를 가져온다고 하셨는데요. 왜 가장 마지막인가요??  [0]을 해도 같은 결과값이 나오는데 굳이 -1로 한 이유가 있을까요?
