직장인에게 꼭 필요한 파이썬-아래아한글 자동화 레시피
특정 탭에 진입할 수 있어야 합니다. 이렇게 초반에 탭이 3개가 있는 프로세스가 있는 경우 현재는 test2라는 탭이 활성화 되어있습니다. 저는 test라는 탭을 편집하여야하는데 test2를 종료 하더라도 test 탭으로 정확히 이동이 안되는데 혹여 특정 탭에 접근이 가능한 방법이 있을까요? 우선 현재 띄워져 있는 창의 탭 이름을 가져오는 것에는 성공을 하였습니다. from pyhwpx import Hwp hwp = Hwp() documents = hwp.XHwpDocuments for i in range(documents.Count): doc = documents.Item(i) doc_name = doc.FullName if doc.FullName else "저장되지 않은 문서" print(f"문서 {i}: {doc_name}") if 'test.hwpx' in doc_name: selected_doc = doc selected_num = i break if 'selected_doc' in locals(): # 해당하는 문서가 탭에 존재하면 해당 문서를 편집할 수 있게 선택 만약 탭이름을 활용해서 선택하는 방법이 없다면 hwp.Run ("WindowNextTab")을 통하여 현재 탭의 이름과 하나하나 비교하여 일치하는 경우까지 이동하게 하는 방식이 나을지 아니면 탭에 접근하는 방법이 있을지 질문드립니다.

예시는 9번문제로 질문을 하지만 9번문제 뿐만아니라 다른 문제를 풀이하는데 있어서 괄호 사용이 헷갈려서 질문드립니다. 대충 대괄호하나는 시리즈로 불러오는거고 대괄호 2개는 데이터프레임으로 불러오는걸로 알고있었습니다. 그런데 문제를 풀면서 왜 groupby함수나 sort_values함수를 포함한 기타 다른경우에 소괄호안에 대괄호없이 컬럼명만 사용해도 되는지 궁금합니다. 컬럼명을 쓸때 대괄호를 써야할때와 필요없을때의 구분을 어떻게 해야할까요? import pandas as pd df = pd.read_csv('/content/drive/MyDrive/Colab Notebooks/members.csv') df['subscribed'] = pd.to_datetime(df['subscribed']) df['year'] = df['subscribed'].dt.year df['month'] = df['subscribed'].dt.month df['day'] = df['subscribed'].dt.day df = df.groupby('month').count() df.sort_values('subscribed').index[0]

[퇴근후딴짓] 빅데이터 분석기사 실기 (작업형1,2,3)
이제 막 2유형 공부중인데, 궁금한점이 있습니다. 2유형의 경우에는 답이 없는 문제인 것 같은데, 시험에서 요구하는 제출형식(인덱스 제거, 파일명 맞추기 등)에서 감점되는 것 외에 감점요소가 있을까요? 2유형 만점을 목표로 하고 있는데, 최소로 확보해야하는 성능이라던지의 최소치? 등이 있는 문제인지가 궁금합니다!
