python -v 명령의 역할

python -v 명령의 역할

최근에 macOS를 다시 설치했는데 파이썬 버전을 확인하고 싶었어요. 단말기에 입력했는데 이게 무슨 짓인지 모르겠어요? 나는 터미널과 파이썬 프로그래밍에 익숙하지 않다. 제가 실수로 새 소프트웨어를 설치했나요?

이 명령은 에서 파이썬 인터프리터를 실행하는 데 사용됩니다. 이 명령어가 실행되면 , , 를 포함한 Python 프로그램의 실행에 대한 자세한 정보가 표시됩니다. 디버깅 목적과 파이썬 프로그램의 내부 작동을 이해하는 데 유용할 수 있다.

디버깅 이유로 인해 모듈이 로드되는 방식이 표시됩니다. (이 경우에는 기본 모듈만 해당)

설명서:

당신은 아무 잘못도 하지 않았어요. Python(에서 액세스)의 man 페이지에서 다음을 수행합니다:

   -v     Print  a  message each time a module is initialized, showing the
          place (filename or built-in module) from  which  it  is  loaded.
          When  given twice, print a message for each file that is checked
          for when searching for a module.  Also provides  information  on
          module cleanup at exit.

   -V ,  --version
          Prints  the  Python  version number of the executable and exits.
          When given twice, print more information about the build.

소문자를 "verbose"라고 생각하면 모듈을 디버깅하는 데 유용합니다. 나열한 모듈은 모두 표준 라이브러리에서 가져온 것입니다.
