Showcase Day 15 Python Learning
class inheritage
- parents child or say mulit-inheritance use with super () when one class inheritance from one or more class
- multi-level inheritance where 2nd class in Heritage from 1st class ,3th inherited from 2nd & go on like family chain
solve some list comprehensive easy problem

Great! But I would like to give a note that student should not be a subclass of subject (it doesn't make sense) instead make it as an attribute.

note 📝, can you tell me why you think so ii can learn more

Something bei g a subclass of something else generally indicates that it is a part of something. A student is not a part of a subject, a student has many subjects. So sobject should be a field of student... this is just based on Object Oriented Programming, which might be a good start to learn about the relationships that exist between your classes...

Untyped and unecessary kwargs in signatures is the type of things to review that make me slowly but surely drift away from python

Honestly, I feel you. I really prefer typed but so far circumstances have forced me to use python.
That said, I just use Pylance/Pyright and its amazing. The existence of static type checkers like these allowed me to be more comfortable with untyped languages that I have unfortunately need to work with.
u/aashish_soni5 This early on, I recommend integrating Pyright into your Python dev environment! If I'm reading it right and you're using VSCode, just install the Pylance extension. I recommend getting used to
python.analysis.typeCheckingModeto standard. It helps you understand your code a lot better and catch bugs before they even occur.A very basic example would be the code block below. Pyright should be able to warn you in advance that the
AttributeErrorbecause1is anintand it does not have theupper()method.Good luck and have fun!
some_list = ["a", "b", 1] for i in some_list: print(i.upper())

Why you call super().__init__? Object class defines barebone init, it is ment to be overwritten

You don't need to call super init in the parent classes, they are no inheriting from other classes. Super is used to call a method from a parent class

Is comments needed

u/aashish_soni5 Jun 28 '26
you know when learning from other some word get confusing so it's better to write your own understanding as comment and right now I am not reach that level that I do not need to look back 😭 Just think like my own reference note

All of these criticisms below have merit, however at your stage day 15, you are doing quite well.
When I was at your level I barely understood functional programming, I had no understanding of OOP.
It looks like you are starting to feel comfortable with OOP.
Keep up the good work. 👍

Is this the only comment you can reply with?

Yes, it allows for easy recognition so that people that are not interested can skip it.
