Amazing !!! Just began my journey into Python programming. Even though some these concepts flew over the head, really enjoyed your explanation. Like and subs from India !!!
Thanks for the video. I have a comment on the polymorphism portion of the video. It is NOT polymorphism though it aligns with "many forms" meaning. The polymorphism demonstration in the video has nothing to do with polymorphism, It is purely typecast (and has to do with the fact that Python is weak-type/dynamic-type language) which means that the type of a variable is derived from the type of the value it refers to The below explains what you demonstrated: a = 7 # a refers an int type object a = 7.0 # a refers a float type object polymorphism means that a variable that refers an object of certain type can refer another type (like in C++ where a pointer to base class type can point to derived class type either). but this can not take place in Python, as the interpreter changes type of a variable according to the type of the data that variable refers to Due to the dynamic-type nature of Python, I'm afraid that Python has no polymorphism though so wrongly claimed
Your explanations are wonderful! when we inherit the class we add one parameter in the derived class(say faa_id in the Airplane class). but you have not explained how to display that added parameter when we invoke the model. will you please explain how to display that too.
I am still working through lessons, was stuck for a long time on the arcade lesson, which I think was really cool to test us on. I had to go back and make sure I really understood what I was doing. I made my own rps style, same code but did a lot more variations with fstring's and emojis. Though I did a lot of it correctly on the guess number game I was still blown away with differences in your code. I had to go back and try look at some of those lessons. I am very slow at this. I am not planning a career but a making a personalized app. I don't think it is going to be a very complex program but still have a lot of learning to do before I can start on that. Oh yah my arcade didn't work correctly because I had a return to game function where it should have just been return game_blabla without the (). I thought I was never going to find the problem. I want to say it was RPS code where the issue was, been a few days since I found the issue.
3) Hi, Sir my question is how many topic you will cover in upcoming days? Or how many days it will take? Actually my exam is coming in upcoming next month.
Your getter would be more helpful if it `returned` something, rather than `print` something. Properties typically return something, and don't do something.
Nice content and learner but Python does NOT have Polymorphism concept in OOP sense as we know it e.g like in Java using overloading , overriding methods because Python is DYNAMIC language . your "polymorphism" here is according to Cambridge dictionary not in programming sense :) hope this helps

It is NOT polymorphism though it aligns with "many forms" meaning.
The polymorphism demonstration in the video has nothing to do with polymorphism,
It is purely typecast (and has to do with the fact that Python is weak-type/dynamic-type language)
which means that the type of a variable is derived from the type of the value it refers to
The below explains what you demonstrated:
a = 7 # a refers an int type object
a = 7.0 # a refers a float type object
polymorphism means that a variable that refers an object of certain type can refer another type (like in C++ where a pointer to base class type can point to derived class type either).
but this can not take place in Python, as the interpreter changes type of a variable according to the type of the data that variable refers to
Due to the dynamic-type nature of Python, I'm afraid that Python has no polymorphism though so wrongly claimed

Love your stuff as usual Dave
Thanks!
3) Hi, Sir my question is how many topic you will cover in upcoming days?
Or how many days it will take?
Actually my exam is coming in upcoming next month.
I cover one Python topic per week right now. There are likely at least 6 more videos in this series.
Your getter would be more helpful if it `returned` something, rather than `print` something. Properties typically return something, and don't do something.
Thanks you, Sir.
You are most welcome
A one shot or playlist of videos on Java Script will be great ....!

Many Python resources cover polymorphism. I'm doing the same here. It's not "my polymorphism".
@@DaveGrayTeachesCode I see what you mean now I get it thanks
