처음에는 다음 데이터 프레임이 있고 그룹 별 및 집계를 수행하여 겹치는 시간 범위를 연결합니다. 최종 데이터 프레임에 다른 열을 추가하고 싶습니다.이 열은 겹치는 행의 데이터를 연결하여 형성됩니다.
df['newid']=(df['START']-df['END'].shift()).dt.total_seconds().gt(0).cumsum()
print (df.to_string(index=False))

보시다시피 마지막 데이터 프레임에서는 ELEMENT, START 및 END 열만 얻습니다. 그러나 내가 얻고 싶은 것은 집계 과정에서 TEXT 열을 연결하는 데이터 프레임입니다.

누구든지 도와 주시겠습니까?
메소드를 집계 할 수 있습니다 str.join.
(df.groupby(['newid','ELEMENT'])
.agg({'START': 'min', 'END':'max', 'TEXT': ' ; '.join})
.reset_index(1))
출력 (TEXT 열만) :
