I need your help to solve an issue of my programming course, I have an initial activity and do not know where to continue, I need to create a program that gets 2 grades, disappear and divide by two generating the average. (I managed to do this) Now I need to implement the program if the student has the average less than 6 the program should request that a new test be done (I was able to print this message if the if is less than 6) only after this message it should give the following actions:

Action 1 if Note 3 is greater than Note 1 replaces Note 1 and sums up and divides with the rest.

Action 2 if note 3 is greater than note 2 replace note 2 and add and divide with the rest.

Action 3 if grade 3 is less than the two grades, display the failed student message.

Follow my code, I’m lost to be able to carry out these actions.

def main ():    

  nome = input('Nome do Aluno: ')
  ra = input('RA do aluno: ')
  print('Inserir notas de "0 a 10.0"')
  nota1 = float(input('Prova 1: '))
  nota2 = float(input('Prova 2: '))
  media = (nota1 + nota2) / 2
    
  if media > 6.0:
        print('O aluno ' , nome, 'de RA' , ra, 'foi Aprovado com a média ', media)
  else:
        nota3 = float(input('Aluno não passou, favor insirir nota da prova 3: '))
      
      
        maior1 = nota3
    
        if maior1 < nota1:
            maior1 = nota1
        if maior1 < nota2:
            maior1 = nota2
    
        if maior1 == nota3:
            if nota1 >= nota2:
                maior2 = nota1
        else:
            maior2 = nota2
    
        if maior1 == nota2:
            if nota1 >= nota3:
                maior2 = nota1
        else:
            maior2 = nota3
    
        if maior1 == nota1:
            if nota2 >= nota3:
                maior2 = nota2
        else:
            maior2 = nota3
    
        media = (maior1 + maior2)/2
        if media>= 6.00:
                print('O aluno ', nome, 'de RA ', ra, 'foi Aprovado com a média ', media, )
    
        else:
            print('O aluno ', nome, 'de RA ', ra, 'foi Reprovado com a média ', media, )
main ()

I thank you in advance for your help!

python if else

  • I believe you reversed the comparisons in your if with nota3 and the last condition must be if nota3 < nota1 and nota3 < nota2

  • I created a few more command lines, but I still face problems with the code. in the validation part

  • In the else is not to inform a condition. This elif media<6: has no sense because it will only be executed if media >= 6.0.

  • Well, I took a look and did not understand why the function, try to take it (if it is not requirement of exercise); has the reversed signs of conditions, as already commented; the first print after the condition is with the third note enclosed and will not read, will give error (I say from what I know so far, despite being a beginner); the last 2 prints are for the same thing, take one, ah and remember to indent in the right condition. See if it works there.

One way to do it is with the use of Elif.

def main():
nome = input('Nome do Aluno: ')
ra = input('RA do aluno: ')
print('Inserir notas de "0 a 10.0"')
nota1 = float(input('Prova 1: '))
nota2 = float(input('Prova 2: '))
media = (nota1 + nota2) / 2

if media > 6.0:
    print('O aluno ' , nome, 'de RA' , ra, 'foi Aprovado com a média ', media)
else:
    nota3 = float(input('Aluno não passou, favor insirir nota da prova 3: '))

    #Com o uso do elif fica melhor de fazer, ja que ele só vai execultar quando o if for falso.
    if nota2 > nota1 < nota3:
        nota1 = nota3
    elif nota3 > nota2:
        nota2 = nota3

    media = (nota1 + nota2) / 2

    if media >= 6.00:
        print('O aluno ', nome, 'de RA ', ra, 'foi Aprovado com a média ', media, )

    else:
        print('O aluno ', nome, 'de RA ', ra, 'foi Reprovado com a média ', media, )

main()
