쉘 실험
파이썬 쉘로 돌아와서
아래 그림은 마지막으로 파이썬 쉘을 확인했을 때의 모습입니다. 물론 여러분 창의 메시지는
순서가 조금 다를 수 있겠죠.
우리 프로그램의 메시지가 파이썬 쉘(줄여서
‘
쉘
’
)에 출력되었습니다. 하지만 쉘은 더 많은
기능을 제공합니다.
>>>
프롬프트를 이용하면 파이썬 코드 명령문을 입력해서 즉시 실행할 수
있습니다. 이때 명령문에 출력할 내용이 들어 있다면 쉘에 그 결과가 출력되고, 값이 들어 있다면
계산된 값이 출력됩니다. 만일 새로운 변수를 생성하여 그곳에 값을 할당했다면
>>>
프롬프트에
변수명을 입력하여 값을 요청해야 출력됩니다.
아래 예제를 확인해보세요. 여러분 쉘에 예제 코드를 직접 입력해보면 더 좋겠죠? 각 프로그램
명령문을 입력한 다음 엔터 키를 누르면 쉘이 코드를 즉시 실행합니다.
쉘은 명령문을 실행한 결과를 화면에 출력합니다.
엔터 키 누르는 것 잊지 마세요.
계산식을 입력하면 쉘은
계산 결괏값을 표시합니다.
값을 변수에 할당하면 값이 출력되지 않습니다.
값을 출력하려면 명시적으로 쉘에 요청해야 합니다.
