OOP Class Inheritance and Private Class Members - Python for Beginners!

Hi everyone! today we will do a quick classes and objects exercise!
We will practice everything we've learned in previous tutorials and we will also talk about:
🐍 class inheritance
🐍 private class members... and why they're not exactly private in Python 😅
🐍 in the very end - tips of how to avoid repetition!
In our exercise - we own a guitar store and we need to find a way to keep track of our inventory.
So through a variety of real-life examples, we will discover all the qualities of classes along with their significance!
You can either follow along in your IDE or you can:
⭐ Clone My Tutorial Code ⭐
* Sorry code is unavailable, RIP Wayscript 😭😭😭*
If you have any questions - please leave me a comment below and I'd love to help! 😊

I'll be honest I thought she was classic click bait: hot chick + interesting topic = views, but she does break down the core concepts in an easy and engaging way.

[@PythonSimplified]

hahahaha thank you so much Design! 😁 I'm super happy you liked this tutorial and even happier to see you summarized the entire purpose of this channel in one sentence! 😀😀😀 Trying to take some difficult concepts and make them approachable for everyone, so thank you so much for your lovely comment!

[@wesleyphon508]

can this be simply with dataclass or even pydantic -hmmm

[@wesleyphon508]

simplfy

[@wesleyphon508]

simplify - sorry my key get stuck

[@TomkinsOkello]

You present complex programming topics in an easier way so much so that newbies understand the concepts explained.

[@PythonSimplified]

Thank you so much Tomkins! 😁 That's exactly my goal with each tutorial, super happy it shows! Thank you for the lovely comment! 😃

[@tehpimpmasta]

Not to mention, make coding look sexy asf. 😅 😍🤤🥵🤩

[@romanhaskelsky969]

One small tutorial has done more than all the other lessons in the last 6 months! Thanks!!!

[@powersprouter]

Thank you!!!! Your tutorials are a gold mine - you really are talented at making confusing subjects much easier to understand.

[@mkhadka123]

The best thing about your videos/explanation is that you make complex topics in programming such as OOP so much fun to watch and understand them clearly at the same time. It feels like learning when we were children.

[@internetchild]

Wow! This is by far the best tutorial I've come across. Thank you :)

[@murtazabadshah1535]

WOW amazing tutorial. You explained the concepts so clearly. I finally understand the self notation and what it's used to for. Thank you so much! Please keep uploading more tutorials :)

[@RicCarden]

Amazing. You took 12 minutes to clearly explain what I've spent 2 days trying to get my head around. I've got it! You have a real talent for teaching. :-)

[@tiramercu]

This is so much more understandable than my university lessons. Thank you so much!

[@calebsuit5390]

Your videos are the most helpful python tutorials I have found. You are a great instructor. Please keep making more great instructional content.

[@DucatiSydney]

You are the best teacher! Very polite in communication, attention to detail is impeccable (you don’t forget or fail to explain any details like () something like that). The way you take time and not rush things really helps a beginner to follow along, although English isn’t my native language, I could pick up all the jargons and technical terms and relate to it smoothly. Feels great to discover your channel. more videos please! .upper()

[@SLTechnologyBest]

Dudeee till now i was struggled on OOP. It's mad how simply you explain these stuffs great work no words to explain woaaah. Continue the good work

[@joereality1664]

I've learned Python for work and have been using it regularly for work projects. I just gotta say, even watching these beginner videos again after some time is teaching me new things. She's dropping little nuggets here and there that explains so much that I didn't fully understand until getting more familiar with OOP. Absolutely gold. And she's great at breaking it down and explaining!

[@americovaldazo6373]

As a guitar player, this is the best example to learn classes and inheritance in Python. Thank you very much.

[@Novacasa88]

You have an exellent teaching style and presence. Good work. Enjoying your videos.

[@eduarmafla6148]

I have beeb quite awhile learning python. YOU are the best tutorial person that I have experienced teaching python and more. and you are the smart, everybody should learn from you.

[@Khigha87]

Thank you so much for this video. I was struggling with OOP and reading words from a few books provided only marginal clarity. Your singing surprised me, I don't know why I didn't expect you to sing well lol. Your singing ability is second only to your ability to explain coding concepts. Thanks again!

[@stefaniafiorucci9826]

I love the way you teach! So simple 🎉

[@novicetech1]

Another amazingly useful video. Thank you.

[@user-ec4hz2ft6h]

This was perfect for beginners like me, I combined this with the free practice exam and study guides i found on Learnology World, although those materials were useful for me to prepare for the type of exam questions that i should be expecting in the exam, these video was good in helping me understand the course better, all essential topics was mentioned. thank you very much ❤ i really appreciate

[@obajiokereke4028]

so much covered in this video... kudos..highly recommended

[@noelremasu]

You are such a great tutor, I wish I had you as my mentor or lecturer at university

[@aguypassingby1945]

Thank you, Mariya!!! You're awesome!

[@DominikZalewski85]

Best explanation I saw on YT! You are such a positive and funny person and great at teaching. I'm surprised you have 100k subs "only" ;)

[@freedtmg16]

Wow this really helped me understand classes as a whole a lot better across all languages. The examples you used were so much better than (pet eat or family cat or whatever I usually see) thanks!

[@PythonSimplified]

hahahaha yeeey!! I'm super happy you found my tutorial helpful! 😀 I'm gonna film an additional practice tutorial soon, this time using vehicle classes and inheritance. We will draw different types of vehicles in a recent Pygame project, so this time we'll see an extra visual example (which I believe is the best way to learn 😉)

[@anthonyrojas9989]

Your videos are fun and informative! Thank you

[@fbravoc9748]

Amazing tutorial !! Thanks!

[@artaniskim2120]

As just as what Albert Einstein said "If you can't explain it simply, you don't understand it well enough." I was struggling with the OOP and you simply nailed it for me. Thank you so much. looking forward to see more videos from you !.

[@anthonypretty2877]

I'm quite astonished you don't have many more subs as I have viewed hundreds of related videos and yours are , by far, superior in both the presentation and content explanations. Class first!

[@Dragons927]

A gorgeous example of a class guitar!

[@validol696]

Thank you so much from Ukraine! 🌹 You explain everything very clearly!!! Subscribed

[@breamgarces4680]

there is a print function in the class and yet explicitly called outside the class. I think it is best to write return("pam pam pam pam...") then call it outside the class as print(my_guitar.play()). I am still learning python and I am catching a "none" error. I am not sure about my solution though but it works in my end. Thank you and keep providing quality tutorials! Love from the Philippines!!!

[@Manopatz]

best tutorial for using multiple class !!!!

[@AbhiKumar-oc6qw]

Very good explanation of this topic. Thankyou so much for this and this explanation is very helpful for me.

[@johnlj_ciscocertified]

well explained, thank you for this video it will help me on my Cisco DevNet learning and certification.

[@sgarrison05]

I have read and watched other explainations on this topic. By far, this was the best explaination with easy examples. I have the basic and always felt like the intermediate topics are not covered quite as well or often. Thank you for your dedication.

Thanks for your classes. You broke down a hard nut to crack for me.

[@suvimpemel5583]

This was a great tutorial for me. It so happened to be that I new these things and I never new where to use and why to use. The best part is I'm a bass guitarist, the examples you took are really striking to me. Also the song "House of the rising sun" is a song that my brother and I use to play instrumental on.

[@PythonSimplified]

Thank you so much for the incredible comment Suvim! I'm so happy you found this video helpful! 😃😃😃 "House of the rising sun" is one of my favourite songs to play! it has super easy chords and everybody knows it by heart! I usually replace "New Orleans" with "Hastings Street" as I live in Metro Vancouver so it's quite appropriate! hahahaha (it's a really nasty street!) I think it's absolutely awesome you play bass! We can almost start a PythonSimplified band with Ryuya Sho on the drums and you on the bass! We only need lead guitar and we're good to go (I have a feeling that your brother might be able help with that)! 😊 I don't think many people know this - but I've been singing in a heavy metal band when I was younger so the music vibes are strong with me! 😉 Now I only have my classic guitar, my voice and my audience which consists of my spouse and my cat hahahaha (unfortunately all my bandmates are on the other side of the planet and it's not as fun to write music on your own - I've always seen it as a team activity! 🙃)

[@suvimpemel5583]

@@PythonSimplified wow, I would love to play the bass if you are putting up the band together. Yes my brother plays the lead guitar. He is much better on production side. I'm pretty sure your audience is mesmerized by your talent and my prayers on your bandmates.

[@ornellatortorici]

Thanks a lot for this tutorial! It starts to become clear in my mind! :D I have to build a GUI with a Python program for work and I just found your kivy tutorial, which was great! I love your way of explaining things and your good energy is contagious :) I started to learn Python years ago but was still stuck on learning about object language and classes, and I was always avoiding it. Now I start to feel more confident about it :) Just a question about this tutorial: so there's no way to store confidential information? I was expecting you to show the good solution after showing that the private members is not a good one 😅

[@varsketisLT]

You are my favorite python teacher, thank you so much! Now working on my first kivy app, which I started half a year ago, then things in life happened and I just stopped working on it.. Picked it up a couple of days ago and voila! Already created my own settings screen with a json file to dump the settings into; already have 2 languages (en and lithuanian) built-in, and also I'm starting to really know what I'm doing. Hopefully my github page will have a single completed project soon :D This OOP tutorial just cemented everything I have thus far learned. Thank you so much!

Wow, I was struggling for few days to understand Classes in python. In the beginning, I simply didn't watch your videos more than 1 minute bcoz I thought a hot chick trying to get some extra views. But I saw your videos popping up multiple times and start watching complete videos. Damn, she is one of the best python tutors out there. All my doubts are clear now. Thanks 🙏 for such amazing videos.

[@GregThatcher]

Thanks!

[@marvinnunez3037]

Such a great tutorial!!!! As a basic python course student I have learned a lot of hits from this tutorial. Dealing with OOP, do you have any tutorial where uses a dictionary as an attributes in a class construction? I need to work on a project with a patient record with id, name, lastname, phone number, address and health conditions and drugs (last two as a list). It will be very appropiate because I can use the id as a key and the other information as another dictionary...
