Is it possible to do such a system in Python, let's suppose on a college system if I put
materias = print(input("Digite o número exato de matérias que há nesta série: "))
What it takes to repeat the same amount as the person put type like
print(input("Digite o nome da matéria: "))
I want to repeat this question and separate each one into a "string" to later put the media of everything and several other things, but the focus is this, I wanted to know if you have how to do this.
I did not quite understand the part of the averages, but here is a solution to your problem storing issues:
materias = []
qtd_materias = None
while not isinstance(qtd_materias, int):
try:
qtd_materias = int(input("Digite o numero exato de materias que ha nesta serie: "))
except:
print('Por favor digite um inteiro')
for _ in range(qtd_materias):
materias.append(input("Digite o nome da materia: "))
print('As materias sao:', ', '.join(materias))
If your intention is just to have a list of materials stored as a string, you just need to use a list, and Python has a certain ease regarding list manipulation.
See an example based on what you described:
i = 0
materias = []
quantidadeMaterias = input("Digite o numero exato de materias que ha nesta serie: ")
while i < quantidadeMaterias:
materia = raw_input("Digite a descricao da materia: ")
materias.append(materia)
i += 1
for m in materias:
print(m)
Entry (Number of stories in the series)
2
Entry of materials
Portugues
Mathematics
Output of materials
Portugues
Mathematics
I just needed to create a list that is the variable materias and then populate it through the loop.
I do not know if I understand your question well, but I think you need a list of subjects and a dictionary for each subject. The result would look something like this:
[{"nome": "Matemática",
"serie": "quinto ano",
"professor": "Paulo",
"alunos":[{"nome": "Maria Antônia", "media": 7}, {"nome":"Renato", "media": 8}],
"mediaTotal":7.5},
{"nome": "Matemática",
"serie": "sexto ano",
"professor": "Rosa",
"alunos":[{"nome": "Suzana", "media": 7}, {"nome":"Claudia", "media": 8}],
"mediaTotal":7.5}]
To mount this structure, I thought of a type code like this:
nMaterias = int(input("digite o número exato de matérias que há nessa série"))
materias = []
for i in range(nMaterias):
materia = {
"nome": input("Qual o nome da matéria %s: " %(i+1)),
"serie": input("Qual a série da matéria %s: " %(i+1)),
"professor": input("Qual o nome do professor da matéria %s: " %(i+1)),
"alunos": None,
"mediaTotal": input("Qual a média da matéria %s: " %(i+1)),
}
materias.append(materia)
print (materias)
Well, of course it would need a bigger work to do another loop to fill each student and the total average could be done with a quick calculation of the filled averages.
In addition, in your code, you can not store print () in a variable. First you store the input in the variable and then you give a print () command.
If I understood correctly, you can do this:
materias = []
n_materias= int(input("Digite o número exato de matérias que há nesta série: "))
for i in range(n_materias):
materias.append(input("Digite o nome da matéria: "))
print(materias)
If you run the code it will do something like this:
Type the exact number of stories in this series: 2
Type the name of the article: Mathematics
Type the name of the article: English
['Mathematics', 'English'] #contents array array
