Dear Sir, Thank you for your efforts and teaching. I have very good learning by your videos. One query I have, In this video in OverLoading part, Where you have used example of NONE for a,b,c. I tried with '0' instead of None and it saved if,elif and else code and Results were same as you have shown. It this method with '0" will work fine, or this NONE can be used in diff scenario? Let me know your view point.
Sir instead of assigning None to a , b , c variable in sum method , we can assign it to zero . So that we no need to check the None value of the arguments.
Sir your content is very very good .Although you take some time to post a video but the quality that we get is very good which compensates everything.Sir we can even wait for a year if the content is good so sir take some time and keep on posting such awesome videos on python because you are our only source of knowledge. :)
Good video, but i would not write that func. like that def sum(self, a=None, b=None ... ) What if we have more than 4 variables. I would write that function like this: def sum(self, *args): s = 0 for a in args: s += a return s Thanks again
Hey Telesko! I love the way you give examples :-)I m 18 years old and I m learning python through your videos /////thank you very much for making this python series:-);-) I love you a lot for teaching me python

"My phone overrides my father's phone", Thank you for being such a wonderful teacher and for sharing your knowledge with the world. I'm looking forward to continuing to learn from you!
Navin, this quick-learn course is awesome...I have been in the industry for 34+ years and decided to learn Python. I did not want to go to 3-6-9 month course and was looking for a quick overview. Excellent work. Keep it up. I have been programming since 1984 and have used almost all languages and platforms....OMG - there are so many things to remember to accomplish this smart programming using Python. I hope "Go" is not further difficult to learn....
Awesome videos sir 👌👌 & it's fun watching your videos while going to office daily. I never get bored & it's really very easy to recall all the concepts the way you explain them. Hats off to you. I loved the example you gave Nokia & Motorola 😃😄 Keep going sir 😄
Sir, How can we use input function for fetch more than one values from keyboard in a single line... like in c we use scanf(" %d %d ", &a, &b); For Fetch two integer values From keyboard in a single line... how can we do it in python?????
Thank You sir for your amazing videos. But sir while method loading instead of using None in default parameter if we assign the value 0 to it we won't require the condition part that is if else part.
for the one how dont konw this method class student: def __init__(self,m1,m2): self.m1 = m1 self.m2 = m2 def sum(self,*a): return sum(a) s1 = student(58,69) print(s1.sum(5,6))
hey i got this override symball on my pycharm ...how to remove that symball ....its created by pressing some random key on keyboard...i dont know how to remove it know .....its overriding methods in objects...may i face any problem due to this symball??
Method overriding also works in same class: class A: def add(self,a,b): return a + b def add(self,a,b,c): return a + b + c A1 = A() print(A1.add(10,20)) --------------------this will give an error print(A1.add(10,20,30))--------------this will give 60------- first definition of add() takes self + two arguments but second definition of add takes self + 3 arguments.. so second definition overrides first definition of first add() method
Class students: Def __init__(self,M1,m2): Self.m1 = M1 Self.m2 = m2 Def addin(Self,a=self.m1,b=2): Return a + b S1 = students (44,65) Print (S1.addin()) I am getting S1 is not defined error.. please let me know how can we assign 44 value to a

Hi Navin, I work in NIIT Technologies and in my project, we don't use python. I've gone through your videos (till this point), and I'm making my notes as well. But I've noticed that I tend to forget what was taught in previous videos. So, have to jump back and forth. If python was used in our project, then, it would have helped me to practice. But for now, apart from the small assignments, I have nothing much to practice on. Can you please suggest what my next step should be? So, I keep on practicing. Regards, Parth Narang
Sir I am from humanities background and currently working as a professional Interior Designer. I am 31years old and recently my partner suggested me to have a look into your videos when I told her I want to learn Python. I have no prior knowledge of coding or anything but after seeing and watching your videos I must say I am in love with the way you teach. If I can ever switch my career from being a designer to a developer of coder, I would thank you from the core of my heart. I am learning so much from you. Thank you once again.
I will never forget about Method overriding in my life. Thank you:)

"My phone overrides my father's phone"
Simply brilliant!
Yes!
That was a very good example.
The Way You Explain Every Concept With a Lovely Example Makes Learning Python So Easy. Thanks Navin Sir❤️❤️❤️.
min 5:40 , def sum(self, a=None, b=None, c=None): , i use (self,a=0,b=0,c=0): , and then we dont need to use "if a != None" etc conditions. 3 lines of code instead of 6 =))
Was unable to understand the concept of Method Overriding. But the way you taught this concept, was amazing. Great job!
i would have NEVER understood this topic in my university. you made it so simple!!
class Student:
def sum(self, *b):
c = 0
for x in b:
c += x
return c
s1 = Student()
print(s1.sum(5, 6, 5, 4))
can we use this for method overloading?
The best example of method overriding.. I will remember it definately
for method overloading using variable length method
class student:
def sum(self, a, *b):
s = a
for e in b:
s = s+e
return s
s1 = student()
print(s1.sum(4, 5, 6))
what a explaining sir.....!
who are dislike the
Videos understanding very well and teaching is awesomeeee
"I was not having a phone.", sounds so Shakespearean.
Sir you are the best your teaching skill is fantabulous keep it up.
Thanks sir please daily upload a video 🚴🚴
your teaching is best sir thank you for such content.😀
Nice and easy explanation. Thank you so much. :)
Very nice Explanation ✌️
The eg.was just remarkable.
The effort u put to make us understand is just insane.
Salute to sir.
As per me, the better option for method overloading would be:
class A:
def sum(self,*a):
c=0
for i in a:
c=c+i
return c
a = A()
print(a.sum(10,20,30,40))
Enjoying this session very much sir😊😊😊
Dear Sir, Thank you for your efforts and teaching. I have very good learning by your videos. One query I have, In this video in OverLoading part, Where you have used example of NONE for a,b,c.

It this method with '0" will work fine, or this NONE can be used in diff scenario? Let me know your view point.
Sir, You are really great in teaching.... Thank you😊😊
Sir instead of assigning None to a , b , c variable in sum method , we can assign it to zero . So that we no need to check the None value of the arguments.
My point exactly
Or maybe to any number you want🤷🏻♂️
def sum(a=0, b=0, c=0):
I think you want to say this👆
Even i thought that bro.
Sahi Bat hai.
Thank you Mr. Reddy! I really appreciate it.
This guy has answer for any question. Awesome work Navin Reddy...
sir very good example you had taken
"i understand the concept perfectly now"
thank u for this
At 6:15 for method overloading, it would be better to pass 0 than None as we can skip that if condition.
What if you pass strings as arguments
Excellent use of example - easy to understand! Thank you
i Am watching your videos from years, just know your methods are simpler for beginners. and for everyone keep it up.
Sir your content is very very good .Although you take some time to post a video but the quality that we get is very good which compensates everything.Sir we can even wait for a year if the content is good so sir take some time and keep on posting such awesome videos on python because you are our only source of knowledge. :)

last exmaple was awesome

Awesome concept. Seriously sir, you teach in a great way. I will be looking for your next videos to understand the usage of this concept in depth.
"My phone overrides my father's phone", Thank you for being such a wonderful teacher and for sharing your knowledge with the world. I'm looking forward to continuing to learn from you!
good explanation of method overriding
instead of (self,a=None,b=None,c=None) we can (self,a=0,b=0,c=0) to avoide conditions

Hi Sir,
In Method Overloading, instead of using None can we use zero.
Is there any more memory usage of using zero?
Awesome videos sir 👌👌 & it's fun watching your videos while going to office daily. I never get bored & it's really very easy to recall all the concepts the way you explain them. Hats off to you. I loved the example you gave Nokia & Motorola 😃😄 Keep going sir 😄
Overriding is same as MRO(Method Resolution Order), right??
"Method Overriding " love u sir,u r god
Nokia 1100😍
We can use it as a weapon as well
Ult battery
Nicely Explained :) ...but I have a doubt here
what is the difference between duck typing and method overriding
6:07 you don't need that lengthy code just set default values of a, b, c as 0
Yes
we can put by default zero to sum method instead of none its working fine zero also
Sir will you please make videos on data structure with python..
Sir, How can we use input function for fetch more than one values from keyboard in a single line...
like in c we use
scanf(" %d %d ", &a, &b);
For Fetch two integer values From keyboard in a single line...
how can we do it in python?????
a,b=int(input()) , int(input())
Sir you said i make more videos on this topic interfaces , abstract classes sir please make videos on this topics
We are learning python from you, where you learnt it from?
Thank You sir for your amazing videos. But sir while method loading instead of using None in default parameter if we assign the value 0 to it we won't require the condition part that is if else part.
you made me emotional i remembered my old days
for the one how dont konw this method
class student:
def __init__(self,m1,m2):
self.m1 = m1
self.m2 = m2
def sum(self,*a):
return sum(a)
s1 = student(58,69)
print(s1.sum(5,6))
Another day of thanking God for tutors like you who I owe my engineering degree to.
Sir please make a video series on different modules of Python
hey i got this override symball on my pycharm ...how to remove that symball ....its created by pressing some random key on keyboard...i dont know how to remove it know .....its overriding methods in objects...may i face any problem due to this symball??
kya baaat :) beautifully explained
it is a very good idea to have tutorial for practices, in which after watching tutorial of the concept we can learn better via practices. thank you
Method overriding also works in same class:
class A:
def add(self,a,b):
return a + b
def add(self,a,b,c):
return a + b + c
A1 = A()
print(A1.add(10,20))
--------------------this will give an error
print(A1.add(10,20,30))--------------this will give 60-------
first definition of add() takes self + two arguments but
second definition of add takes self + 3 arguments.. so second definition overrides first definition of first add() method
Class students:
Def __init__(self,M1,m2):
Self.m1 = M1
Self.m2 = m2
Def addin(Self,a=self.m1,b=2):
Return a + b
S1 = students (44,65)
Print (S1.addin())
I am getting S1 is not defined error.. please let me know how can we assign 44 value to a
Cant we use *args or **kwargs instead?
Write a python program using recursion to traverse every single element of the nested
list.
[10,20,15,[11,”hello”,25.5,[123,15,”hi”,[10,20],52],100,200],15,50,[51,”welcome”],1000
]
sir please send me answer
Simple trick
class Miles:
def sum(self,x= 0,y=0,z=0):
sum=x+y+z
print(sum)
r1=Miles()
r1.sum(1,3)
class Miles:
def mul(self,x= 1,y=1,z=1):
mul=x*y*z
print(mul)
r1=Miles()
r1.mul(1,3)
class Meth():
def __init__(self,aa,bb,cc):
self.aa=aa
self.bb=bb
self.cc=cc
def add(self,a=0,b=0,c=0):
s=a+b+c
return s
gvn=Meth(3,4,5)
print(gvn.add(10,20))
simpul overloading
i think i will not forget this overriding concept . thanks man.
class Student:
def sum(self,num1=0,num2=0,num3=0):
print(num1+num2+num3)
s1 = Student()
s1.sum(5,8) # 13
# can this be done for method overloading?
But exactly why python does not support overloading?
while explaining the Method Overloading, if we set the values of a,b,c to 0 like a=0,b=0,c=0 then we don't have to do all the checks using if condition ? we can call even with a single arg and it would still work
we ca define sum like below also
def sum(self,a=0,b=0,c=0):
return a+b+c
Overriding example is superb
Great explanation! Thank you!
Class S:
def sum(self, a= 0, b= 0, c= 0):
return a+b+c
s1= S()
print( s1.sum(2,3))
#this is also working
#please explain
ohh,, me too till 10th I also don't had a mobile. but yeah you explained very well. your father's phone is urs and your phone overrides
Why do we even need the below lines in method overloading example?
def __init__(self):
self.m1 = m1
self.m2 = m2
Every one of your videos will have 100k views soon. You rock bro.
why are we taking init method in method overloading ? what is the use?
what is the use of line s1=student(58,65)
Method overriding set backs when father have iPhone and I have normal phone....I would say iphone lol😂
Sir, can use **kargs in method overloading
Yes
**kargs for dictionary aruments like key value pair,, if you not sure how many args you are passing just use *args it takes as list ,,,args and kargs are just convention you and use any names but *, ** important to note
I just confused another vedio saying another ypu are saying this about method overloading i can't just u understand
wooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooooowwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwwww
if python is a horse then u are riding over it....
I have a doubt in method over loading what is the use if using __init__methods and using m1 and m2 in the above video ???
Good explanation sir
That father son example is just wow 🔥
class My class(str):
pass
print(Myclass("student"))
O/p:--. student
Same thing with int()
After inherit STR we pass string value as a argument in MyClass constructoe but we didn't call any method of STR class
without showing instance in a string format how it print student
Can we create a class and inherit which will work like how STR work in MyClass:
Please reply. Me I know you didn't have a time but I know you never let student doubt to go

Insted of having none we can use default argument as 0 so ther will no use of using if statements.
Can You explain>>>>When to use OverLoading And When OverRiding????????
When i want to use fn overloading with respect to data type, how will i achieve in python
What if my father has a way better phone than me..I will go with the super class.

me wants to learn python - panik
finds telusko - kalm
he uses light mode - panik
one more point what I have learner recently,
dad can not use child 's phone.
but revesre in not true
Yes default arguments will replace if any arguments missed at position..
Story to explain method overriding is superb❤️
Instead of using none we can use zero? Which can make method smaller?
