1 year ago pandas 최신 버전에서 데이터프레임.append() 메써드가 사라진 것 같습니다.
데이터프레임.append()가 데이터프레임을 세로 축 방향으로만 합칠 수 있다면, pandas.concat()은 데이터프레임을 세로 뿐만 아니라 가로 축 방향으로도 합칠 수 있기 때문에 데이터프레임.append() 대신 pandas.concat()을 사용하도록 유도하는 것 같습니다.
데이터프레임.append(데이터프레임) 코드를
pd.concat( [데이터프레임, 데이터프레임] ) 코드로 변경해 주시기 바랍니다.
e.g.)
#df = df.append(pd.read_html(requests.get(pg_url, headers={'User-agent': 'Mozilla/5.0'}).text)[0])
df = pd.concat([df, pd.read_html(requests.get(pg_url, headers={'User-agent': 'Mozilla/5.0'}).text)[0]])보다 상세한 내용은 아래 블로그를 참고하시기 바랍니다. https://ordo.tistory.com/51

Exception occured : 'DataFrame' object has no attribute 'append' 이게 계속 출력되는 것을 보면 아마 def read_naver(self, code, company, pages_to_fetch)이 함수에서 except Exception as e: print('Exception occured :', str(e)) return None 이 예외처리가 되는 것 같은데 어떻게 해결해야 할까요?
IDE 환경은 VS code 나머지 라이브러리와 파이썬 버전은 교재에 기재되어있는 것과 같은 버전입니다. 코드는 올려주신 DBUpdaterEX.py 입니다.
