Generating a student's transcript [OOP concept]

[aongkeko]

Hi,

This is part of my homework. We're trying to learn/apply some concepts of OOP in this exercise.

This is what I've got so far.

def welcome(self):
          print("==========WELCOME==========")

class demographics:
          def __init__(self,my_id,age,gender,location,*args, **kwargs):
                    #super(demographics,self).__init__(*args, **kwargs)
                    welcome(self)
                    print("")
                    #print(my_id)
                    #print(age)
                    #print(gender)
                    self.location = str(input("Are you In-State Y/N: "))
                    if self.location=='Y' or self.location=='y':
                              print("The In-State School Fee is $560.")
                    else:
                              print("The Out-of-State School Fee is $913.")
                                  
class grade:
          def __init__(self,math,science,english, *args, **kwargs):
                    super(grade,self).__init__(*args, **kwargs)
                    ave=(math+science+english)/3
                    if ave > 90:
                              print("Your final grade is A")
                    if ave >80 and ave <=90:
                              print("Your final grade is B")
                    if ave >70 and ave <=80:
                              print("Your grade is C")
                    if ave <=70:
                              print("Your grade is F")

class final(demographics,grade):
          def __init__(self,*args, **kwargs):
                    super(final,self).__init__(*args, **kwargs)
                    demographics(self,my_id,gender,location)
                    print("====Student's Transcript Report====")
                    print("Student ID: ",my_id,"","Age: ",age,"","Location (In-State Y/N): ",location)
                    print("")
                    print(math)
                    print(science)
                    print(english)
                    print("Your average in three subjects is ",ave)

However when I run my code using this example:

x=final(my_id="001",age="33",gender="M",location="Y",math=95,science=100,english=95). I encountered a "NameError" where a variable/variables are not defined. See output below:

Output:
>>> x=final(my_id="001",age="33",gender="M",location="Y",math=95,science=100,english=95)
==========WELCOME==========

Are you In-State Y/N: y
The In-State School Fee is $560.
Traceback (most recent call last):
  File "<pyshell#0>", line 1, in <module>
    x=final(my_id="001",age="33",gender="M",location="Y",math=95,science=100,english=95)
  File "C:\Users\among\Desktop\Assignment 3 Python\Assignment 3 Part 3.py", line 36, in __init__
    demographics(self,my_id,gender,location)
NameError: name 'my_id' is not defined

Thanks very much. Appreciate any constructive feedback.

Best,
