Hello, in this video we are going to look at class inheritance. So this is, you know, fantastic. So instead of having to, you know, create multiple classes, even though let's say one class might have similar functionality to another class, you can do something called inheritance. So we have this vehicle class, what if nothing created a class or did class call, for example, colon, and then we would have all the features, but if we put brackets, and we specify a number, last name for vehicle, so very similar to what we did here, objecting to the built in class, so so that's really sort of just overlooked it at that point, but we've created a car class or we're currently in the process of the hence the error, and it's inheriting from vehicle so what does that mean? pacifically. So let me put here I'm going to call wait Cool and I'll pull the same method as well.

So hopefully we wait and now what we're going to do is just put self don't wait when it increases like so. Okay, all warning errors have disappeared fantastic. So what this means is call has the attribute it has this attribute, but it has access to all of these attributes as well so we can do the increased speed so if we were to create now foiled color on the color equals call for example and let's say if I will To do and for this print, I'm going to put, I am going to put child call dots. Wait, I am going to print out again and then the child call increase weight. And I'm 50 by nine. And now let's also print color dots.

So we'll have access to the speed, increase speed and effort, but we won't, you know, use that moment we can overlook that. If we run it. There we go, we get 10 for the weight. After it's increased, we get 19 foot barrier zero shoes from here. That's the beauty of class inheritance. We can basically absorb functionality from another class.

Especially if it has common functionality because you can think of in real life, you know, we everything is like an object. And you know, you might have furniture that an object part that you might have a table in which will, you know, have legs for example and you know, other features, then you might have a certain type of table and you can just inherit for me so you can just have like a trickle in feature effect. That's it for this video. In the next one, we're going to be covering inheritance a bit more. Thanks for watching and I look forward to the new very, very soon.
