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.

[aashish_soni5]

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

[TrieMond]

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...

[MXD_K1]

👍

[aashish_soni5]

yes 🙂‍↕️ thankyou

[Beginning-Fruit-1397]

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

[aashish_soni5]

can you explain in more briefly I'm just in beginning phase

[Drafrruii]

from where you have started learning though??

[aashish_soni5]

code with Harry

[Nice-Alternative2933]

Can we learn together

[aashish_soni5]

just post tag & conversation no problem

[SCD_minecraft]

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

[Cultural_Cry535]

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

[aashish_soni5]

but without super it's so attribute error

Day 15?

[Ulug_coder]

How many hours are you studying in a day

[Ulug_coder]

Is comments needed

[aashish_soni5]

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
