How to calculate max value using python 3 object oriented programming? [duplicate]

Question

So I'm learning about classes and objects in Python 3, but there's an error in my code ('int' object is not iterable)

Error

class student:
    name = 0
    gpa = 0
    def countGpa(self):
        a = max(self.gpa)
        print(a)

def main():
    objek = student()
    n = int(input("n: "))
    for i in n:
        objek.name = int(input("name: "))
        objek.gpa = int(input("gpa: "))
    objek.countGpa()
main()

I have no idea how to create an array + OOP

Does this answer your question? Python - TypeError: 'int' object is not iterable — user438383

hmm, i still don't get it, because it should be written with object oriented programming... — tinymermaid

There are lots of things wrong here. For a start you create a single instance of student, but you seem to be asking for many names. This implies that you want lots of instances. That would make more sense when it comes time to work out the max() gpa. — quamrana

then, how to create array with oop? before i started with objek.name[i]= str(input("name: ")) but it doesn't work here.. — tinymermaid

Only regarding your error: Convert for i in n: to for i in range(n):

Is it true like this?

listGpa = [] class student:     name = 0     gpa = 0     def countGpa(self):         self.gpa = listGpa         listGpa.append(self.gpa)         print(listGpa)  def main():     objek = student()     n = int(input("n: "))     for i in range(n):         objek.name = str(input("name: "))         objek.gpa = int(input("gpa: "))     objek.countGpa() main()

but why i can't print my array , output is like this [[...]]

The error has been fixed. If you want your code to work properly, you need to put some of your own effort into this as well. At the very beginning it is really frustrating to learn coding, but keep it up! ;)

'for i in n:' doesn't work like you want. The variable 'n' is an integer and You want an array. You want 'for i in range(n):' which creates an array of the numbers one through n.
