Python abstract classes 👻

Python abstract class example tutorial explained
#python #abstract #classes
#abstract class = a class which contains one or more abstract methods.
#abstract method = a method that has a declaration but does not have an implementation.
prevents a user from creating an object of that class
+ compels a user to override abstract methods in a child class
from abc import ABC, abstractmethod
class Vehicle(ABC):
@abstractmethod

pass
class Car(Vehicle):
def go(self):
print("You drive the car")

Thank you

Sir basically what's the use of it , for what. Purpose we're going to use it

Your intentions are clear - Simply educate and not show off smartness by complicating the content, which other channels do. Keep up your work.

[@forrestelliott3267]

This was really helpful, thank you. Though I think at 4:57 the error arose from the vehicle = Vehicle() line, not from the motorcycle = Motorcycle() line, as your commentary implies at that moment.

[@yevhenliubarskyi1841]

Thank you Bro, your explanations are just crystal clear. I've already watched several of your videos. Hope you achieve great success with your channel.

[@yuilhan4275]

Thank you, your explanations are clear and is easy enough to understand.

[@Muertedertod]

finally someone that is able to explain this clear and short! THX a lot!

[@beingzero7541]

Wow!

[@horoshuhin]

this is such a concise and to-the-point explanation of ABC. I've yet to find a better one. and probably don't need to anyway. thank you

[@henriquefelinimena7433]

Thank you Bro!

[@nirutg5130]

I find 6-7 sources from internet to understand about Python abstraction but not understand!, just understand from this video. Thank you so much Bro.

[@sirenhanced6248]

Thanks so much I have a test for my Python OOP course tomorrow on this you saved me.

[@TheHansdampf80]

Thank you

[@Vertig_Pro]

Keep doing gods work bro

[@soklin]

Thank you!!!

[@HussainAli-sb1dv]

love u

you are a genius bro. thanks 🙂

[@tarikyassa1076]

Thanks Bro!

[@fellowstepchicken7555]

Thanks bud !

[@rubenc4696]

Thanks

[@shavindasilva]

best BRO :)

[@SmokyDesperado91]

Thank you, great explanation! I have one question though: is there some way to create abstract attributes in analogy to abstract methods? I want to make sure that those attributes will be implemented in all child classes

[@timhiggins7072]

Bless you for making this more clear than my professor.

[@anfedres]

cool video bro... ps: Turn of the cc... it is hilarious!

[@umarhasnain7369]

Ya. Haha🤣.

[@uuhju7004]

nice

[@chriskeo392]

More content on abstraction and encapsulation while using dataclasses please

[@harithabandara3212]

Thank youu!!!

[@hangchen]

Thx bro!

[@marianotorres4052]

thank you!

[@jimenadelgado7384]

thaaaanks

[@digosantista]

Cool. But it would be nice to comment on the video (or do a voice over) to let people know that error arouse from Vehicle being instatiated not from implementation itself.
Other than that, great! Thanks!

[@jhontriboyke5534]

thank you bro !

[@cloudroot7]

It's easy to understand the concept.

[@user-cd4zb3gk3z]

Спасибо, видео помогло разобраться!

[@chillydoog]

for the algorithms. ty brother

[@pun15h3r.]

quick and dirty.
nice, thanks!

[@omercagla8970]

Best tutorial I have ever seen

[@lw9954]

ty bro

[@xBaphometHx]

Clear as water!!!

[@kerry7932]

Nice video. I think we need some additional information about the purpose of abstract classes as many of the comments have indicated. That is, is if subclasses cannot inherit from their parent, what is the purpose of the parent?

[@lovelyaashik9732]

Sir basically what's the use of it , for what. Purpose we're going to use it

[@Bro-cc8pw]

What's up bro

[@user-ew7ri4gk2l]

You are very clear and objective. But I can't understand the use of abstract class if you can't instantiate it and the same functions are written bellow in other classes???
Thanks in advance.

[@santosbogo]

I am doing python at university and this is the best video Ive ever watch

[@nazarsilchenko8326]

Instant like for mentioning the need for speed:)

[@samiam.402]

I might've missed it, did he explain why you don't have to "super()" the methods you are overriding? Is this an inherent part of an abstract class, or am I missing something?

[@Craulback]

super() gets the child class access to the attributes from the parents method, it doesn't override anything, but is useful when your child class needs the same attributes, plus some new one.
class Child(Parent)
def __init__(self,attribute_1,attribute_2,attribute_3)
super().__init__(attribute_1,attribute_2) # this will pull the first 2 attributes (of the same name) from the parent
as for overriding, just defining the child's method using the same name as the one in the parent will override it for the child class.
it looks for the "go()" method in the child class, before looking for the one from the parent.
so it never actually encounters the abstract version of the method.

[@sebastianradlmeier8922]

​@@Craulback Thanks for the explanation

[@shingaling3315]

I understand the implementation but what is the purpose of doing this? I’m not following what benefit was gained by going through this versus not defining an abstract class at all

[@sterlingevans129]

Can someone explain the reason an abstract class would be needed if the child class' methods would be explicitly written anyway?

[@jhassee]

supporting the channel

[@vitaliytysiachnyk5347]

Bro, please add English subtitles, because it's only Vietnam. Lol
Thank you!

[@SxlarSiren]

WE LOVE YOU

[@gattinocurioso6852]

In python can you explain the difference from Abstract class and Interface?
