예) 저장소 이름 : github-action

소스코드 작성

2개의 파일이 필요합니다.
weatherbot.yml
send_to_weather.py

:white_check_mark: .github/workflows/ 하위 경로에 weatherbot.yml 있어야만 GitHub Actions 이 동작합니다!

동작 확인하기

github-action 저장소에 위에 작성한 weatherbot.ymlsend_to_weather.py 2개의 파일을 업로드 합니다.
노란볼을 확인하고 Actions 클릭합니다.
자! 이제 weatherbot.yml 에 작성한대로 일련의 작업이 일어납니다. 이것이 :thumbsup_tone2: Github Actions!
따라해보실래요?
