는 가중 평균

Question

내 코드 역 추적의 오류 (마지막으로 가장 최근 통화)를 얻기를 찾는 데 도움이 필요() 파일 "C :/Users/Daniel Nase/Desktop/assignment 7 test.py", 줄 23, 주 calculate_weighted_average (score_ammount, scores_t, score_weight, average1, num_t) 파일 "C :/Users/Daniel Nase/float ((score_weight.pop (0))/100) TypeError : 지원되지 않는 피연산자 유형 (/)은/test/: 'str'및 'int'

나는 가중 평균을 계산하려고하는데, 내가 뭘 잘못하고 있는지 모르겠다. 도와주세요 !!!!

그것은 당신이 문자열과 int를 곱 위해 노력하고 있다고하지만, 당신이 그들을 분할하려는 것이 아니다

(오류 메시지가 /하지 * 말한다).

final_weight = int(input("What is the weight of the final?(0-100) ")) 

scores_t[i] = int(input("Please input test score #" + str(y) + " ")) 

scores_a[i] = int(input("Please input assignment score #" + str(y) + " ")) 

scores_q[i] = int(input("Please input quiz score #" + str(y) + " ")) 

input 항상 문자열을 반환하고, 당신이 그것을 밖으로 번호를 얻으려면, 당신은에 있습니다 : 당신이 그랬던 것처럼 당신은 쉽게 이러한 라인,하지만 int 또는 float에 문자열을 변환 할 수 있습니다 그것을 변환하십시오. 당신이 여기에서하지 않았다 : 여기

score_ammount[x] = input("How many " + score_type[x] + " are there?") 

및

 score_weight[x] = input("What is the weight of all the " + score_type[x]) 
     total_weight = total_weight + int(score_weight[x]) 

을 당신은 total_weight에 추가하기 전에 정수로 score_weight[x]의 값을 변환하지만, score_weight[x] 자체는 여전히 문자열입니다.
