Create a student class

[santhosh_8]

Create a student class which has following functionality:

• Initialise a student with mandatory parameters
• Create a student with name, email and phone number
• Add a list of subjects based on which class he is
• Add a function to calculate his percentage based on marks scored

I have written C++ code of student database. I want python code so please anyone write in python and share asap.
Thanks in advance :-)

You neglected to add bullet point 4

• Post your code so I don't have to do anything myself

[santhosh_8]

Please send your mail id @Reverend Jim, because I am not able to upload that file here. Help me to writing the same it in python. Thank you.

[Reverend Jim]

Post the code using the code block tool </>.

[santhosh_8]

Here is the code screenshots. Thank you.

As above, use the </> Code Block feature when posting otherwise you end up with fuzzy hard to read pictures that no one can copy, edit and paste their ideas.

[Reverend Jim]

It also makes it possible to (in some cases) copy/paste code if someone wants to do local testing to help you out.

[santhosh_8]

Sorry for the inconvenience.
PFA.

[rproffitt]

@san. The code will fit inside your post. Why would you have us open up Word or other apps to get at your code.

Again, when you post use the </> Code Block so your code is here and ready to read. Make it easy on everyone.

That's getting there. The </> Code Block allows { and } so next time you create a discussion you can avoid character substitution.

OK, so there's your code. As you can guess this is some assignment so you get to write all the code. What's stopping you? What line is a problem?

[santhosh_8]

I want the same code in python.

[rproffitt]

I guess something wasn't clear here. No one writes code for you unless it's some one liner or not much more.

Besides your first sentence is something you see in a homework assignment. https://docs.python.org/3/tutorial/classes.html tells me that yes you could create a class for that object so you have that going for you.

As to a Python version, that's your work unless you are putting it out there for pay.

Here is the python code of student management system. I'm not able to print any data after running the program.

class Student(object):

    def __init__(self, name, roll_number, mobile_number, email_id, section, subjects, obtained_marks, percentage):
            self.name = name
            self.roll_number = roll_number
            self.mobile_number = mobile_number
            self.email_id = email_id
            self.section = section
            self.subjects = subjects
            self.obtained_marks = obtained_marks
            self.percentage = percentage

            print("A student object is created.")

    def get_details(self):
       "Returns a string containing student's details."
       return "%s Student details %s" % (self.name, self.roll_number, self.mobile_number, self.email_id, self.section, self.subjects, self.obtained_marks)

    def print_details(self):
        """
        Prints the details of the student.
        """
        print("Name:", self.name)
        print("Roll Number:", self.roll_number)
        print("Mobile Number:", self.mobile_number)
        print("email-id:", self.email_id)
        print("Class of Student:", self.section)
        print("List of subjects:", self.subjects)
        print("Total marks out of 600:", self.obtained_marks)

        perc = obtained_marks/600*100
        percentage =(float)(perc)
        print("Percentage:", percentage)

Why would you expect any output? You've defined a class with methods but you haven't created any instances of that class. You code doesn't have any mainline section so nothing is being executed.
