오류 : 나는 '1'게임 '을 플레이하기 입력 할 때

이

Traceback (most recent call last): 
    File "C:\Users\Boys\Desktop\3 Round Quiz.py", line 24, in <module> 
    if difi == ("Easy"): 
NameError: name 'difi' is not defined 

오류가 위 온다 변수 difi가 퀴즈에 대한 것이지만 숫자를 추측하십시오. 왜 이런 일이 일어나는지 모르겠으니 어떤 도움을 주시면 감사하겠습니다!

if quiz == 1: 
    print("Would you like to play 'Easy' or 'Hard'?") 
    difi = input() 

당신은 그렇지 difi를 설정하지 않고, 이름이이 경우에 정의되지 않은 : 감사

Answer 1

difi는 quiz가 1 인 경우에만 적 바인딩됩니다. 당신이 '2'를 선택하지 않는 한

quiz 0에서 시작하고는 증가하지 않습니다 :

elif game == ("2"): 
    quiz = quiz + 1 

당신이 '1'을 선택하면, 다른 한편으로는, quiz 0 유지, difi가 설정되지 않은, 코드가 깨집니다.

Answer 2

difi이 정의되기 전에 제어 흐름이 if difi == ("Easy"): 행에 도달했습니다. quiz이 여전히 맨 위에 0이기 때문에 제어 흐름이 정의되어 있습니다. if difi == ("Easy"):과 관련 코드 부분이 더 들여 쓰기되도록 지정 했으므로 if quiz == 1: 블록 안에 나타납니다.
