그러나 어떤 이유로, 내 코드가 제대로 작동하지 않습니다 그것은 첫째 인쇄

을 줄이 같은 화면에서 : 내 자신의 코드를 썼습니다.

어두운 방에 있습니다.

이 오른쪽으로 문이며, 당신이 취할 감히 어느 어둠

의 전체,

그리고 중간 경로를 왼쪽?

그런 다음 입력 할 때마다 프로그램이 오류를 발생시킵니다. 나는 이유를 모른다.

이 게임을 도와주세요.

대단히 고마워요. :-)

첫째, 질문 할 때 오류 메시지를 포함해야합니다.

    if haunted: 
NameError: global name 'haunted' is not defined 

이것은 Cthulhu를 떠난 직후에 발생한 오류입니다.

여기서 문제는 haunted이 exchange_path 함수 내에 정의되어 있다는 것입니다. 문제는 함수 내부에서 정의 된 변수가 해당 함수에 대해 로컬이므로 다른 함수 내부에서 사용할 수 없다는 점입니다. 이렇게하면 두 개의 unqiue 변수가 생깁니다 (같은 이름 임에도 불구하고).

간단한 해결책은 (권장하지 않지만) 변수 haunted 실제로 것을 파이썬에게 키워드 global를 사용하여 다음 asked_for_help 및 times_in_exchange_path과 함께 스크립트의 매우 시작할 때, 가장 외부 범위에 haunted을 정의하는 것입니다 지역 변수가 아닌 전역 변수.

일반적으로 전역 변수는 사용하지 말고 대신 매개 변수로 변수를 전달해야합니다.
