Challenge: Modeling a Farm
00:00 So as always, if you don’t practice it, you don’t really understand it. It’s all fine and well to watch slides and nod and say, yeah, yeah, that makes sense. But until you actually have to write it yourself from scratch, things don’t really click. Your challenge is to model a farm.
00:16
You don’t want to let things go ahead of yourself, but you do want to try and use all the tools that you’ve learned so far. So here’s a suggestion. Model four classes, say one Animal class and then three classes that inherit from Animal.
00:30
Each class should have a few attributes and at least one method, maybe making sounds, eating, sleeping. Maybe they should be variations for the classes that inherit from the Animal class. Then try and model two more classes, maybe a Field, maybe a Barn.
00:47 Maybe these can even have a parent class.
00:51
Then make these places have an attribute where they can store Animal objects. So you’re starting to model a farm where you may have cows in one field and then you move them to the barn, and maybe the barn already has some pigs and some horses.
01:06 Maybe you feed the animals with other classes that can represent foods. Maybe each animal has a level of hunger and enjoyment. Get creative with it. But again, don’t get carried away with it.
01:21 But try and put into practice everything you’ve learned in this course so far.

@Pythagoras thanks for your feedback! We’ve actually been experimenting with just the format that you’re mentioning in the File Systems Operations course. On the Python Basics Learning Path, you’ll see an associated extra course called Python Basics Exercises: File System Operations.
Let us know how you like the format if you get a chance to take a look, we might roll them out for more courses if our subscribers think that it’s a good idea :)

Hello!
The tutorial was helpful, and the information was explained in a clear way. I agree with @Pythagoras. Having an extra video that shows how you solve the challenge after trying on your own would be super beneficial. That would allow us to see what mistakes were made, if any, and clarify some concepts. I’m surprised none of the tutorials includes that. Is there a way to get a review of the solution?
Thanks, Katya

@Katya Since these courses are based on the Python Basics book, you can find the corresponding exercises and their solutions there. For various reasons, it was decided not to show the solutions in some of the videos. In the meantime, I’d encourage you to share your solution on the Real Python community Slack, asking for feedback or help if you get stuck anywhere. Alternatively, if you have a specific question, then you can post it under the relevant lesson, and we’ll be happy to answer!

Some constructive critisism.
Happy with the your tutorial of classes and object orientation. Plenty of information to try to grasp but still not exhaustive to keep the learning- momentum optimal and not getting stuck on too much details.
That said, having a video of you doing the challenge after giving the participant the opportunity to think and do it for themselves is something that would be beneficial. Getting immediate feedback after trying for yourself on a blank slate truly elevates the learning-potential. Quite surprised to see that none of the tutorials have this.
