Python 을 활용해 간단히 출력하는 기능을 만들 수 있다.

#파일 입출력 시작
f = open("data_s.jsonl", 'w', encoding="utf-8")
f2 = open("data_f.jsonl", 'w', encoding="utf-8")

while 조건식:
    print(data)
    f.write("{\"prompt\": \"" + 변수 + "\", \"completion\": \"" + 변수 + "\"}\n")
    f2.write("{\"messages\": [{\"role\": \"system\", \"content\": \"" + 변수 + "\"}, {\"role\": \"user\", \"content\": \"" + 변수 + "\"}, {\"role\": \"assistant\", \"content\": \"" + 변수 + "\"}]}\n")

#파일 입출력 해제
f.close()
f2.close()

또는, 다른 라이브러리(json 및 전용 라이브러리) 를 활용할 수 있다.
