python NameError,하지만 그 이름이 정의 된 것 같아요

Question

좋아, 내가 LPTHW를 통해 가서 게임을 쓰고. 우리는 게임을 가져 오는 것이 어떻게되는지보기 위해 게임을 다른 스크립트로 구분해야합니다. 나는 4 개의 스크립트를 가지고있다. ex45.py은 주 코드를 실행하는데, Engine45.py은 엔진이고 Locations45.py은 위치 목록이고 Maps45.py은지도 값을 보유하고 위치를 이동하는 것이다.

실행할 때 내가 오류는 다음과 같습니다 역 추적 (마지막으로 가장 최근 통화) : 파일 "ex45.py", 2 호선, 수입 Maps45 파일 "C에서 : \ 사용자 \ Raistlin \ 파이썬 \ Maps45. 파일 "C : \ Users \ Raistlin \ Python \ Locations45.py " 'Gold_gym'지도 라인 6 : Gold_gym(), 나가서 설명하자면 NameError : 이름이 'Gold_gym은'나는 골드를 얻고 이유를 이해하지 않습니다

을 정의되지 않은 _gym은 Locations45.py에 정의 된 경우 정의되지 않습니다. 아래

Answer 1

당신이 :

모듈 Locations45

그래서 네임 스페이스에서 가져온

import Locations45 

는 결코에서보고 알 수없는,

Gold_gym() 

그것은 그 객체에 대한 Maps45에 보이는 전화 Locations45.

변경 라인 읽기 : 당신은 그냥 import Locations45을 할 경우

locations = { 
     'Gold_gym' : Locations45.Gold_gym(), 
     'Sapphire_gym' : Locations45.Sapphire_gym(), 
     'Cerulean_gym' : Locations45.Cerulean_gym(), 
     'Loser_gym' : Locations45.Loser_gym() 

Answer 2

, 그것은 이름의 각을 가져올 수 없습니다 - 대신, 그것은 그룹으로 가져옵니다. 당신은 기간 사용하여 그룹 내의 개별 사물을 참조 할 수 있습니다 : 또는

'Gold_gym': Locations45.Gold_gym(), 
'Sapphire_gym': Locations45.Sapphire_gym(), 
'Cerulean_gym': Locations45.Cerulean_gym(), 
'Loser_gym': Locations45.Loser_gym() 

을, 당신은 특별히 이름을 모두 가져올 수 :

from Locations45 import Gold_gym, Sapphire_gym, Cerulean_gym, Loser_gym 

을 그 이름을 사용할 수 있도록 것이다 접두사를 사용하지 않고 .
