[python] crontab을 통해 Python 스크립트 실행

Linux crontab을 사용하여 Python 스크립트를 실행하려고합니다 . 이 스크립트를 10 분마다 실행하고 싶습니다.

나는 많은 해결책을 찾았지만 그들 중 어느 것도 작동하지 않았습니다. 예 : /etc/cron.d 에서 anacron을 편집 하거나 crontab -e. 이 줄을 파일 끝에 넣었지만 아무것도 변경하지 않습니다. 서비스를 다시 시작해야합니까?

*/2 * * * * /usr/bin/python /home/souza/Documets/Listener/listener.py

이를 구성하려면 어떤 파일을 편집해야합니까?

다음은 스크립트입니다.
