Dear CS Dojo, Thank you so much for these. I'm a newcomer in coding, and as an adult, I'm embracing every error I make as an opportunity to learn new things and correct existing faults. I hope to become a computational linguist after my future masters, and I'm determined to get there. Keep up the amazing content

[@561Aloha]

wishing you the best

[@anytutorialforyou]

I have been learning so much from you and the androud app SoloLearn! 2 weeks ago I couldn't print "Hello World" to save my life, now I am reading sensors and finding it much easier to actually understand and learn from other's codes. Anything I don't get in SoloLearn, you help me understand in the video, and if I don't understand what you're explaining, SoloLearn has my back! Please never end these types of videos, you are an amazing teacher and obviously have a big heart to leave your job and help others such as myself. Keep on keeping on, I look forward to learning much more from you!!

[@rahultirkey7950]

You just saved my life. You're like an angle who came to help me. Keep making more videos to inspire more people who loves to code but don't know where to start.

Best series on youtube on this topic! I'm happy you brought up this point at 6:39 about changing the constructor. I was asking myself why you didn't just do it that way on the part 1 video. Glad I watched this to clear that up. Thanks!

[@adarkdwarf5950]

these videos are the best tutorials I can find on KZbin, so keep up the great work.

[@martinkaspar5095]

hello dear CS Dojo wow - a really overwhelming tutorial - very helpful and in all things Python. I like the sidenotes that you give to the idea and concepts that are used in JAVA. This is very interesting. I really like this ideas and your "CS-Dojo approach". Well your stuff is among of the very best python-ressources on the whole net. One question though can you put togehter the most important infos into a cheatsheet - a Summarizing Cheat Sheet to download: that would be fantastic. Above all: dear CS Doyo - you did a fantastic job explaining these concepts of Python programming! I am learning to code and your introduction helps me to fully grasp the ideas. keep up the great work - it rocks!! best regards martin

[@cybertaopodcast]

Hi CS Dojo, Please continue with your series of Python, it is really great to learn this programme with you. Can't wait for the next video.

[@atlantic_love]

If you paid attention, he said said he wasn't. Not in OOP anyway.

[@hyesungoh410]

One of the best tutorials I've ever used!

[@ButterBeanCW]

This really cleared up the difference between methods and attributes for me. It’s interesting that you can create an object and the set new attributes on that object with the “.” and then the new one. However, you can also call a method in a class in reference to an object constructed on that class and interact with attributes to do a function. Cool!

[@marqwithers]

Thank you for making these awesome instructional videos. I've learned more here in a just few days than any programming class I've taken previously. Please keep going with this!

Hey Cs Dojo your tutorial is full of wonderful stuff, I learned about Object Oriented Programming with python also I can apply this on other Programming language because you taught smooth like professional speaker.

It seems like this is the final tutorial of the series. Any suggestions as to what exactly I should learn next? I was thinking on jumping into a framework like Django and/or Flask, but I'm not sure if I should start learning that with only the basics shown in these tutorials.

[@CSDojo]

I'd suggest Lynda.com or Pluralsight after this. I'm thinking of starting a new series with Django or Flask soon, too!

[@tokpengeng1818]

Hi may i know what is the reason of creating method, def sit_down(self):and def stand_up(self):which never been used in your demo?

[@ruthwaiganjo2550]

Hi, thank you for the course. I am really understanding Python. A few questions. 1. If I change the name of the attribute is_sitting in the constructor, does it affect the sit_down and stand_up methods? 2. How do you use the sit_down and stand_up methods? How do they relate to the is_sitting attribute and what is the importance of those methods? 3. How come we have a new attribute robot_owned which has not been defined anywhere?

[@ruthwaiganjo2550]

So I've rewatched the part one video where you state that Robot() is a default constructor. But in part 2 we already had a constructor in the person class...does that mean you can always add attributes to your objects using the dot method irregardless of whether the constructor is the default of one that you have defined?

[@iseeflowers]

Yes. I’m confused with robot_owned which came out of nowhere. It was never mentioned in classes and it just became an object?

[@Ugufugu95]

hey guys, I just stumbled upon this tutorial now and I have the same issue as you - it is puzzling to me why the console didn't throw an error after assigning to this undefined variable a value (a whole robot object) have you maybe during those years developed the knowlegde to explain that? :)

[@rockguitarist8907]

Lol i was looking for someone to comment on this to see what answer is. We didn’t set up robot_owned as a method or attribute anywhere, so I don’t get how Python recognizes it without throwing an error. Guess I’ll keep learning and it will come to me.

[@TusharGaurav]

i have difficulty in passing object as argument in your video session 6:52 how can i passed the object of robot to the Person constructor so that i can get which robot belongs to which person...

[@aungthiha5416]

It willl be like this: class People: #Construtor def __init__(self, pname, page): self.name = pname self.age = page #.......... def Information(self): print("He is " + self.name + " and " + self.age) p1 = People("Aung Thiha Tun", " 19 years old.") p2 = People("Nandar Aye", " 22 years old.") class Student: def __init__(self, n, na, per, iss, p): self.name = n self.nationality = na self.personality = per self.is_setting = iss self.people_owned = p def is_sitting(self): self.is_setting = True def standing(self): self.is_setting = False s1 = Student("Aung Thiha Tun", "Myanmar", "Loyalty", True, p1) s2 = Student("Nandar Aye", "China", "Aggressive", False, p2) s2.people_owned.Information()

Amazing Big Bro Continue

[@joeyzalman8254]

Your explanation is amazing

[@true911m]

I've enjoyed your tutorials so far. They're to the point and share some nice extra tips without being over people's heads. Practically speaking, though, I'd like to know about handling IO in Python, maybe in a desktop app, command-line app and a web app, if they're (probably) handled differently. I can look it up, but it seems like a pretty basic need in any app. :) Keep up the great work and thanks for considering my request.

[@neevpatel3670]

print(“ Thank you!”)

[@georgesmith3022]

if you want to learn oop learn java or c#. the fact that you can add properties on demand after you instantiate an object, is error-prone and happens only in javascript and python

[@ajithtolroy5441]

Your classes are amazing brother :)

[@gurmaansidhu8515]

can anyone explain me the last part from 7:47. I got the concept but some confusion in the last code.

[@jiakai7254]

Hi i have a question: can a method (belonging to person class) change the attributes of robot? note to cs dojo: it might be clearer if u say that a robot has an "introduce_self" method rather than function since methods are called on an object, and functions can be called on its own.

[@hingsing1]

please do more python!! Thank you for this video

[@espedale]

Great instruction. Is it considered to be poor form to add attributes to a Class outside of the __init__? It seems like it would be confusing to collaborators as they would want to see all attributes of a Class by simply looking at the consolidated attributes in the original def of the Class. Adding new attributes (like robot ownership) outside of "def Class:" structure seems disjointed and sloppy.

So if you can definitely attributes in line without going back to the class, wouldn't that make it hard to troubleshoot? It looks as if it's not defined anywhere
