class Triangle: def __init__(self, a, b, c): self.a = a self.b = b self.c = c def perimeter(self): p = [self.a, self.b, self.c] h = sum(p) return h t1 = Triangle(3, 4, 5) result = t1.perimeter() print(result)

[@stephelisabeth3143]

In my Python class, it has been hard to understand what you might actually use a class for and how it would be applied. I assumed it had to do with organization but it was hard for me to come up with specific instances and my professor honestly hasn't demonstrated that for us. You made it obvious in two seconds and it will make doing my assignments easier going forward. Thank you for that.

[@ravi2971]

the clearest and most well-explained video on classes on KZbin! Keep up the good work man!

[@cerealkurus]

Trueeee

[@bilkisabe1660]

Very true

[@ndemazizou9866]

True

[@anj6912]

Totally agree!

[@enzy6434]

I’ve watched Python tutorial videos from pretty much all content creators worth anything and this guy is by far the best overall at teaching concepts in a clear and understandable manner.

[@del_f_s_1051]

I am a python beginner learner. I watched a bunch of videos on KZbin but couldn't understand the concept of OOP. This video is an absolute gem. Thank you sir, in just 18 mins every part covered in the video was crystal clear. God bless. 😊

[@abhishekghosh5550]

hey i bought one course of a popular python instructor. couldn't understand that and came here. and got crystal clear man! this is incredible. and here, i was pulling my hair off as to where am i going wrong. Cheers.

[@dots223_]

Finally, a video that clearly explains classes. Thank you!

[@peterchin6759]

Oh man!!!!!! The most concise explanation I have ever heard/ read. The only regret I had was that I couldn't discover your videos sooner.

[@HamzaAli-iy3ws]

You are doing such a great work by helping us in learning python and with such an ease. Keep it up and wish you a great success!!!

[@serpentinefireball]

This is amazing! I watched quite a few tutorials on this topic before I found your video and none of them helped me understand the concept the way you did as a total beginner. Thank you!

[@Another_Username-s9d]

One of the best tutorials. I also like that you actually added a task at the end to check if we really understand

[@zainkhatri5030]

i love you pundit, everytime i have struggle i come to you and you always execute. love from uzebekistan - jamal

[@Huyautomation2901]

I've spent at least 3 days to figure out what the hell are "classes and object" in Python.Wow God blessed me found your video.That's very clear now I totally understand them.Thank you so much ! You got my like button and share

[@kawaiikina3618]

Huge thanks to Programiz team! I can see you guys have devoted a lot of effort into this video. Your script is the most concrete, clearest and easiest to understand. The step by step guidance also lays out the logics clearly and allows beginners to succeed in the programming task later, which is rarely seen in other tutorials. You are great python teachers!

[@forrestt1294]

The Blueprint-House analog helped me. Your teaching employs common-sense. Common-sense isn't very common. This is the best Class/Object video on the net. Thank you for taking the time to make this video!

[@Lekan-i1c]

A lot of people must have said thank you but I will like to say it again. Thank you!

[@tanmayparekh3371]

I have watched many videos but trust me this video is the best i have ever seen.

[@sumanhere99]

I just love your way of teaching..it makes everything clear to me.

[@Buckybarnesfan22]

A true master. I have watched your video many times. It is an extremely clear and concise way to teach OOP. Thank you!

[@kamalelbo5116]

it's the best video explaining classes and OOP, good methodology and very good job,thanks

[@seshasai7348]

Hi bro. Actually I was learning python since 1 month. Since one month what I learnt I never felt confused but today I was confused particularly this concept. Anyway I really thank full your concepts which you brought on screen to make help us.

[@DigitalAcademyOnline]

Learning Python is something you would like to get in your skills, but you do not know where to start? This NEW channel will help you out leaning Python Programming from scratch - for complete Beginners, Intermediate and Advanced Levels

[@MrStarmat]

very clear, thank you very much ! As a newbie as me, concrete examples with step by step explanation on python is very helpfull to get the concept of OOP.

[@Adinasa2]

class Triangle: def __init__(self,a,b,c): self.a = a self.b = b self.c = c def perimeter(self): sum = self.a + self.b + self.c return sum t1 = Triangle(3,4,5) print(t1.perimeter())

[@SoSha_Tv]

Thank you so so much for breaking Class down to be understandable. I am indeed grateful.

[@yashtiwari00008]

This video cleared all my doubts, thank you so much, you taught very well

[@MGrace01]

class triangle: def __init__ (self,a,b,c): self.a = a self.b = b self.c = c def calculate_perimeter(self): sides = [self.a,self.b,self.c] return sum(sides) first_triangle = triangle(3,4,5) print(first_triangle.calculate_perimeter())

[@Niko_Dola]

This is was the most useful tutorial for classes and objects , thank you!

[@samiicosta]

I was reading the Python official tutorial, which is great. But this video made it SO MUCH clearer! Thank you for the lesson. Keep up the good work.

[@jeffnc]

Thank you this was very useful. I liked that you include an exercise at the end too, I feel I have a much better understanding now :)

[@MoonLi8th]

class triangle: def __init__(self, a=0, b=0, c=0): self.side1 = a self.side2 = b self.side3 = c def calculating(self): perimeter = self.side1 + self.side2 + self.side3 return perimeter T1 = triangle(3, 4, 5) print(T1.calculating())

[@hawaiiankickboxer]

FINALLY!!! ....An Indian I can understand. Awesome video!

[@vengalrao5772]

I got understand after many days 🙏❤️...but love this 💙💙💙

[@fadilyassin4597]

well done very good I like the way you explained sttributes as variables and methods as functions it is important to define words first because it removes the confusion of names thanks again

[@sainath2848]

Thank you... Now I got clarity on OOP

[@PerrySullivan]

Legit tysm. Thank god I started taking notes on videos outside of my class. Watched this vid like several weeks ago and I wrote down code about the "Complex" number problem and little did I know, a similar problem like that would appear on my midterm (that I'm taking rn at the time of this comment).

[@vishnug16]

You the awesome trainer for this course in youtube platform ,really you explained all the topics with theory and code. Keep going on

[@thiernoba]

Well done. Very composed and well explained. I finally get it. This seemed like expert stuff for me for a long time, but not anymore. Don't change your tone because, In some other videos, the instructors act like they have to speak fast to come out as they know their stuff.

[@lemikanadeola7442]

this is the best video i have learnt from, and besides... your smile helps understand it better. thanks a lot for the explanation. keep the good work🥰.

[@sudhamjayanthi]

Love the website and tutorials! High-quality content 👌

[@kyawswarthant708]

I am your fan now! Regret that I should check this simplest version first : )Thanks A Lot

[@independent7212]

Keep it up sir... your way of expression and methods are amazing

[@gbolagadeolajide8595]

This was an excellent video. It explained creation of objects so well. Thank you so much

[@rashmihiremath191]

I am glad I came across your channel , you explain in a very simple way . Way to go , keep rocking

[@jacknapster5693]

[@nethravathi2845]

The concept is explained very clearly.. 😊

[@blindhydra]

Great video! You are very skillful at teaching the information and progressing the difficulty, loved the video!! Thank you very much

[@ramonashiah9636]

I am still confused on the [15:27] line 14, the way we called the add method...

[@TheTenorChannel]

Great video. Wish you the best & success!!

[@Qamar92]

What the hell is my instructor explaining for past lecture and tutorial session? I watch this videos and everythings clicked for less than 2 minutes. Thank you for this.

[@chinecheremchima-w1e]

Thanks for making this video, and also for the mobile app.

thanks buddy it was fantastic

[@duncanmwangi3468]

Thank you Sir ,You are a good teacher clearly explained

[@tanvimutha4049]

Very well explained! Thank you for great work.Can't wait for the upcoming videos.

[@edulel]

Excellent and very clear explanation of classes in Python!!!! I will suggest using different names of variables inside and outside of the class (result) to better understand the examples. Thank you!!!

[@kaila-annguiste1472]

so clear and easy to understand quick!

[@kumarprmshvm565]

Your Videos are awesome, Man. Maybe it is not know to many.. I strongly believe you will succeed in u r mission

[@kajalchandravanshi2456]

I found this very useful. Thankyou so much sir.😊😊 plzz keep uploading these kind of videos cause it will help a lot of students who are in search of crystal clear concepts with good examples.

[@frankharrigan5368]

Thank you so much for explaining OOP in such an easy to understand way. You've been a great help. I've subscribed to your channel.

[@NARASIMHAM1002]

Great work! Keep up the spirit and this channel will grow very soon.

[@hemre1913]

[@Nancivlog]

very clear... i hve subscribed keep up the good work

[@John-eq5cd]

Very clear, well worth watching. Thank you

[@creativecodz]

superb classes sir. thanks for making such amazing python class videos. one request sir if possible please make videos on real-time projects with explanations for beginners. so that we will be more confident in programming. once again thanks a million sir

[@abusufian7848]

wonderful!!! Love from Bangladesh, Brother!!!

[@gabrielnino2892]

This is so helpful! thank you!

[@sarahooshmand1830]

Thank you, this video is so helpful and easy to understand

[@haraldurkarlsson1147]

Very clear videos. These concepts can be quite confusing (because of all the code jargon that programmers use).

[@seanhoran5014]

I'm lost on this one, great course thus far but somehow went to another level without any defining on how you got there with this one.

[@JH-KU]

Thank you. very well organized and explained. Well done.

[@pavaraliyanage93]

thank you, sir interesting and very helpful for me

[@pakistan3965]

Sir! what is self and why we use itm

[@ilyadgreyrat5322]

class Triangle: def __init__(self, a, b, c): self.a = a self.b = b self.c = c pass def perimeter(self): return (self.a+self.b+self.c) t1 = Triangle(3, 4, 5) print(t1.perimeter())

[@riadasgupta2737]

very simple and to the point... thanks for making the concept easier

[@sucharithaanumula1849]

Awesome explanation

[@LostHaven]

Very easy to follow, thanks for explaining!

[@Studywithmelilac]

Very clear! Thank you so much sir

[@zubaidahsabah7948]

very well explained

[@sanyamjain4777]

The way you explain ❤️

[@sharanchandrasekaran8399]

Great video, thank you

[@ashisdas5376]

I was waiting for it

[@harshad9203]

Hi, I have modified the code by a bit by asking the values of each side to count the perimeter instead of asigning it so the code is here class Triangle: def __init__(self,a,b,c): self.a = a self.b = b self.c = c def perimeter(self): perimeter_nums = [self.a,self.b,self.c] perimeter_value = sum(perimeter_nums) return perimeter_value value1 = int(input("Enter the first value: ")) value2 = int(input("Enter the second value: ")) value3 = int(input("Enter the third value: ")) result = Triangle(value1,value2,value3).perimeter() print("The perimeter of your given Tiriangle is", result)

[@ashishkarsh5817]

Where to get the solutions??? Of the task you gave

[@mathewschibesa9793]

Great Video bro!!!!

[@jabezs.1913]

It was a wonderful one😜😜

[@saurabhvaishya3896]

I AM ON JUST 3RD MIN OF THE VIDEO BUT STILL, IT FEELS LIKE BEST OF ALL

[@rajwalavalkar7208]

couta>>b>>c; sir, what is equivalent python code for this c++ code? plz reply!

[@laoying20]

Thanks it was very good.

[@derikaem8021]

great explanation! is there a way to have several init functions, so that you can construct an object with a variable number of attributes?

[@adireddy4710]

Just Awesome and super interestingly genuine way of teaching...So thankful to u brother..also please post videos on data science or AI related too if u can ..thank you

[@riyashrestha3483]

It is here!!!
