"This is horrible way to compare two students by marks"
I Love this line👍🙂
ikr
bro i also loved it so much!! what a quencidence
Sir your statement : "marks is not the way of comparing" won my heart
After so so many years, I have finally understood operator overloading!
😱😱😇
Exactly
Still i can't understand operator overloading 😔😓
@@alimdeen6921 YOU ARE RIGHT, THIS GUY Showing his nose after traveling through out the universe, actually he has to tell first simple example then he can show his vaast variety of expereince on us as beginners but directly he showing something else 99.9999999% from that the thing what we need is 0.0000000001% so its very confusing he did same for duck typing also
@@anindian4601 No, Actually his explanation is cool. He is explaining in the beginner point of view
He is probably the best instructor to learn from! He teaches with so much clarity! Hats off!
Since last Monday I have started to watching your videos . Now I am in #60.. , ultimately your teaching skill is too good . I have some basic core java knowledge, that's why I can catch up quickly and without you I couldn't go in depth in python.. thank you very much for sharing those materials . Appreciate your hard work.
You are a talented teacher! Happy that i've found you. Keep up the videos coming
Wow I never knew about these double underscore function. Glad to learn new things from your channel. Thank you sir.
Excellent explanation I ever heard. You are amazing. Your teaching skills are at a peak. Impressed.
One of the Good lecture, Students need teachers like you
I ain't able to figure out the example of operator overloading :(
Thanks, sir! from now on, you opened my eyes on what python can do. All confusions are gone from my head. I really understand python now.
Thanks superhuman for this great explanation, right now I can feel what is happening behind the scene
Clearly explained the concept of method overloading in Python. Thank you!
Thanks for providing quality content for free it's better than most of the paid courses out there .
You are just amazing.(:
The way you explained the connection and flow behind the code was exceptionally well, your video increasing my knowledge of python exponentially.
I was here to learn what operator overloading is. At the time of the end of the video, I learned about the structure and how the things behind the scene gonna work. Take a Bow Navin Sir.
Really I never understand this topic... But nowww i really know the meaning of operator overloading! Hats off to you sir🙌
Sir u literally thrown away my difficulty of understanding magical methods 🔥
Finally in this tutorial somethings I couldn't understand started making sense, thanks to this man!
this is the best channel on youtube to learn coding
Best Tutorial series in youtube ..........Love Sir
This video was very informative. Feels good to understand how magic methods works. Thanks Navin Sir!
Awesome sir...
Also being an educator, I can imagine how much effort you are putting in these videos.👍
How cruel are these language developer, can they not make this little easy....
@@harshavardhandsh5190 Python is easy thou
I can also see the effort you put in these videos, Navin sir. And today is my birthday Navin sir!
great sir again the imformation which will add some values in my life😍
Excellent video...finally understood the concept
thank you for your amazing lessons sir.
def __str__(self):
return " ".join(map(str, [self.mark1, self.mark2]))
This is one hell of a great video! Thank you
Great explaination!
Its crystal clear for me now.
thank you for your excellent class...I felt very very happy..thank you sir
Ur python videos are awsmm.. watched all ur videos on python . waiting for next videos on python..pls keep making videos on python..thankuu sir
Best Way one can teach ! Appreciative content.
After waching video in sequence this is the firts video i enjoy in diff way. ;)
Great video, got lots to learn thank you so much 😊
Awesome lecture.
Thank you sir 🙏
Thnx very much I'm having exam tomorrow very nicely explained
Your classes are amazing...
Thanks a lot sir you cleared my doubts
You're an awesome teacher!
your explanation is excellent
sir, can you make videos on REST API using python
hat's off guruji, im glad that people are aware about the marks comparison way, i aint a fan that way either. but as you said on youtube it might have reached a mass crowd...
Are concepts really so easy,or it's his teaching that's making them??
Just Enjoyed It Thanks
This is good and just.
Thank you.
As useal greater explanation sir💯💯
Sir what next after this basic ?? Blockchain or advance python??
Thank you for uploading these awesome lectures, Sir. There's a typo in this video though. "Syntactic Sugar" instead of "Synthetic Sugar".
Hi sir will you teach advance python like networking with python etc...
amazing concepts
Excellent explanation
When you print an object (and everything in Python is an object), it calls automatically the __str__ method, so we don't need to call it. 'print(s1)' would be enough to do the trick.
sir please bring up a series of python for intermediate where we can understand advance concepts of python.
Excellent Sir .. now I feel like a coder 😁
00:03 Operator overloading allows usage of operators with user-defined types like strings and classes.
02:02 Python uses methods to carry out operations like addition.
03:48 Operator overloading allows defining how operators work with user-defined classes.
05:36 Operator overloading allows us to define custom behavior for operators
07:28 Python allows operator overloading for custom classes
09:08 Operator overloading allows custom comparison of objects.
10:59 Operator overloading and polymorphism in Python
12:43 Operator overloading in Python allows us to customize the behavior of operators.
Just amazing 😊👍
Thank you sir
Thank you so much!
Can we overload the '__add__' method multiple times inside the same class? (Each method having its own different code)
Amazing video , And an amazing series. can we say that defining __str__ is an example of operator overriding ? also is there anything like operator overriding ?
Good learning point
thank you sir...
This man is a genius 🙌
Grt teaching sir..
thank you a lot ❤
Sir you are passing double values through s1 & s2 but it added only first values of both s1 & s2 ...my question is where second values has gone
I was looking in the comment section to see if anyone has asked this particular question, I have no idea what other people understood !
this is not so easy to understand, you did it also very quickly.. anyway thank u very much ..
Really u r awesome sir
I love you bro!!!
superb..
Sir please make step by step videos on interview preperation....
thank you.
you are just awesome
Sir Your videos are like preparing tastiest Briyani and giving it as service for free 😃🥰🥰
I was frustrated since there’s no custom sort method for heapq. Hell i was Huma switch to c++ , but you explained it greatly
These tutorials are great, but it would be a lot better to watch if the code in the background was a bigger font and/or more zoomed on, couse althought the content is awesome, you can hardly read the code it self.cheers
That's who things should be taught, loved the way you created a some background
also please explain the difference between data type and class.
is int, list , str a class or are they data type?
Hi Naveen,
what are the programs used in Product development Programs
Kindly make video
inside int class in add function self is argument which means add method is instance method.why we are able to call "int.add " it should be object.add()
nice video sir
I have a doubt about these statements will you please explain..
X+y is translated into x.__add__(y)
If x has not implemented __add__ and x,y are of different types then y.__radd__(x) is called. There are equivalent "r" methods for all magic methods just mentioned.
*excellent teaching sir. i think I would get good marks in my 11th standard
Can we directly import sum of marks i.e. m1 and m2 from add method and check them in greater than method instead of again adding marks?
Thanks Naveen, every time I go through your video, I thank you and your team.
How can we know which method is called in the behind if we use a specific operator?
Thank you sir :)
What if we want to add 3 values by method overloading...? 🤔
Like... s4=s1+s2+s3
No doubt, explanation is quite perspicuous.
I am just curious how print(a+b+c) performed behind the scene because __add__ can add only two number
Any Explanation/suggestion will be highly appreciated
it's too late but if you're still curious then variable length argument concept would be used in that case,you would accept the b,c in a list in the formal args and then perform the addition by using required mean like iteration etc
Actually, the __div__(self,other) magic method for operator (/) is only for Python 2.x. For Python 3.x -- as I have found -- the (/) operator call the __truediv__(self,other) magic method.
9:08 LEGEND!!!!!
Hi Navin, I was trying to overload the "__truediv__" operator and could see that its having an issue. Below is my code. Please do let me know, if i am doing anything wrong. BTW, i am using the Python 3 version :-
class Stduent:
def __init__(self,m1,m2):
self.m1=m1
self.m2=m2
def __truediv__(self,other):
m1=self.m1/other.m1
m2=self.m2/other.m2
s3 = Student(m1,m2)
return s3
S1=Student(20,40)
S2=Student(10,20)
s3=S1/S2
print(s3.m1)
TypeError: unsupported operand type(s) for /: 'Student' and 'Student'
sir is this all python videos enough for toget basic knowledge in python..
So amazing sir.. Thank you for the awesome tutorial.
At 1:24 it's supposed to be "Syntactic Sugar"
Thanks!
My professor never explained what this even is, and just zoomed through this. Thanks for explaining so clearly! (I have subscribed!)
Awesome Awesome Awesome
Please sir I need one more video on this topic
Please make one more video on class and __init__
There is no div magic method, please can you tell me for division how it works
Sir,Can u clarify how to get list of inbuilt functions by clicking ctrl?I am not able to get?
Sir can you explain how the if condition (out side __gt__ method) is connected with __gt__ method ASAP
