다른 함수의 변수 사용하기 python

Question

안녕하세요, 이것은 매우 기본적인 개념이며, 나는 그것을 찾았고 전역 변수가 저를 위해 작동하지 않습니다. 변수 score을 사용하고 main 다른 함수를 judgment라고 부르며, 퀴즈의 점수에 따라 사용자에게 어떻게하는지 알려줄 수 있습니다. (바로 그 이유 때문에 내가 가장 아래쪽에 judgment 함수를 호출했습니다. main). 이라는 이름이 judgment 함수에 정의되지 않은 오류가 발생합니다.

Answer 1

당신은 당신의 main() 함수의 범위 밖으로 judgement(score)을 요구하고있다. score 변수는 해당 함수에서 로컬 변수입니다. 해당 줄을 들여 쓰기하여 함수 들여 쓰기와 일치시킵니다.

파이썬에서는 들여 쓰기가 구문 적 의미를 가지므로 주 기능 호출 전에 "주 기능 맨 아래에서 판단 기능을 호출하지"않습니다.

Answer 2

judgement(score)을 main() (모두 스크립트 하단에 있음)보다 먼저 호출하는 것 같습니다. judgement(score)을 main으로 옮기시겠습니까? 그런 다음 main의 로컬 복사본 score이 로컬 환경 judgement에 복사되고 전역이 필요하지 않습니다.
