Computational Thinking Week 1 Graded Assignment Q18

[Jagadesh K]

If the existing data type is already as in list, then we can add the new one to the list(no where it is mentioned as the existing scores are in list type) but the existing marks in integer. So why can't we consider this as an integer.

If the marks of each subject are considered individually, then the datatype could be an integer but when marks for a given set of subjects are considered, it looks like a table, which we can see from the score cards. Hence the datatype is a list wherein each row is a record. 

**This is my interpretation. Not 100% sure it is the right explanation.

Thanks for your reply. 

If this needs to be considered as list atleast we should have a field like Marks → Marks{Mathematics, Physics, Chemistry}.

But we don't have a field here like marks here and all the other things like Mathematics, Physics, Chemistry are given as a separate integers. So the new addition to these items will be integer data type only.

I too have doubt on this question

[Abhishek Kumar]

Actually both interpretation are correct. If we interpret like we have to add scores of three marks in a one go....then we have use list(they would have clarified it in the question)

On the other hand if we consider to store score in different steps then it will be integer. A list can store string ,integer etc.
