Comment "#HarryBhai" if you read this 😉😉
Sir Harry , you made it easy for me to understand the instance and class variables concept
#day66
#100daysofcode
Here again no regret in following the course yet , great for anyone out there starting there code journey.
PS : Happy birthday (random person who wrote that it his birthday)
Bhaiya please make a video on how to change the radius of botton corners in kivymd .......
I need it very soon and i am not getting the proper solution from anywhere ......
Hope you will help me very soon on this Channel .....🙏🏻🙏🏻🙏🏻
I ran the code for class variable and instance variable, the greatest difference I noticed is that if it is a instance variable, which is under the def __init__ block. To use it you need to use the object by calling self. This not the case with class variable. You can call it using the class name or object name. For reference.
"
class employee:
companyname = "Illumina"
noofemployee = 0
def __init__(self,name,id):
self.name = name
self.id = id
self.comp = "comp"
employee.noofemployee += 1
def showdetails(self):
# print(f"The name of employee is {self.name} and id is {self.id} and size of {employee.companyname} or {self.companyname} or is {employee.noofemployee} or {self.noofemployee}")
print(f"{self.comp}")
# a = employee("Rohan",400)
b = employee("Mohan",410)
b.showdetails()
"
That's great observation
please create a playlist on DSA using python language too ! Appreciation from Pakistan....👏
bro dont study dsa in python otherwise you will never get a job.Always prefer c++ or java
@@aadityachoubey3296 So from Global job market perspective, Which is more relevant for learning DSA? C++ or Java ??
Hello, can you please suggest me any other language, because i can't understand Python, it's difficult
Present Sir on Day-66 ✋
exercise 6 solution
class libraray:
books={}
def __init__(self,noofbooks,books):
self.noofbooks=i
self.books=t
i=0
t=0
for i in range(0,11):
print(i+1)
for t in range(0,11):
print(t+1)
i = int(input("Enter a value for i: "))
t = int(input("Enter a value for t: "))
if i == t:
print("The number of books is equal to the books in the library.")
else:
print("Invalid text")
what is the difference in there application? both variables can be accessed and changed in instance level
When we have created two method into class one is instance method and one is class method when we called both method with class name not with object then it's work for both then what is the mean aim to create this method because both method are same to same.
Hello Sie
Sorry to interrupt but I think
ek scenario hai jaha no. of employees
instance variable hoga
It's when a person holds multiple business
and he wants to keep track of each of them
please cprrect me if I am wrong at any piont
Bro, please make a video on how to use github code and make a tool website in blogger.
No doubt, aap ka sab videos mai maja ata hai
Harry bhai please create a java full basics to advance placement course
This topic is so confusing....there is only one difference between them and that is position. Bcoz when we changed the instance to 0.3 the entire thing did not change it changed only for harry same with class so what is the difference?
Same query
Same question, searching for answers in comments and only finding more questions like this
Ok i dont think i completely understood your query but ill try my best to explain what i think happened there someone confirm if it makes sense
companyName is a class variable because it is definied INSIDE the class, and notice how the self keyword isnt used...
when emp1.companyName = "Apple India" is run, you are accessing the variable named 'companyName' of the instance emp1, however companyName is a class variable and here you set emp1.companyName which is an INSTANCE variable, so the companyName of emp1 is no longer a class variable but its an instance variable.
Now whenever you run the showdetails() function, you can now notice that the showdetails() function uses self.companyName, which is referencing to the instance variable. If the class variable has not been changed or altered then the companyName of that object will be a class variable, hence Rohan's companyName was not changed. If you want to change the companyName as a class variable, you should access it using Employee.companyName so here notice that you didnt reference any instance of the class, but referenced the class itself.
To explain this better here is an example:
class Employee:
companyName = "Apple"
...
emp1 = Employee()
emp2 = Employee()
emp3 = Employee()
print(emp1.companyName, emp2.companyName, emp3.companyName) # Output: Apple Apple Apple
# Note that above we haven't changed any of the variables hence they all are still class variables
emp1.companyName = "AppleIndia" # companyName of emp1 is now an instance variable.
Employee.companyName = "Google" # Now we changed the class variable to Google. At this point, companyName of emp1 is instance variable while that of emp2 and emp3 is class variable.
print(emp1.companyName, emp2.companyName, emp3.companyName) # Output: AppleIndia Google Google
I hope my explanation makes sense
superb Harry bhai👍👍👍👍
this course is really helpfull
Kya smajha yaar
Today 18th sep-day 66 completed
I've tried everything but I'm unable to go to day 14 repl , my repl is stuck on day 13

But you proved intensity= consistency
😍😍maza aaya
Thanks
Sir I am present, ar mone ajtho bohot ache che chamaj me aya he thanks ❤
bhai ultimate Java course leke aao 😚
Harry sir please make a tutorial on kotlin there are lot's of tutorial but we can't understand only you 🙏🙏🙏 can teach well otherwise please provide a note like you provided in java
Then,does it mean that compiler searches for instance variables and then for class variables in case instance variables are absent??
Please anyone clarify 🤔
Yes, you're right
Thanks Harry for your efforts
Harry sir please give your tutorial in pdf because the replit are want subscription
at 13:46 what is the difference between line_no: 2 and 6
what is the use of giving a pre defined data to a instance variable...(doesn't it doing the samething as class variable?)
anyone ?
It was just an example, we usually use instance variable for receiving a parameter and class variables arehard coded values. Here Harry just took an example. It is not necessary to have pre defined data as class variable we can also take an hard coded value as instance variable.
@@sujatajena267but brother, instance variable would also do the same job, I don't understand why we need Class variable practically
Harry bhauuu............. LINOD RUclips CHANNEL ka kyaa chhakar haa apke kuch video vaha english me uploads hote ha .........discuss in detailed about this topis.
bat to vhi hui na bro agar class me company name= "apple" kare to vo sare instance me jaiga,l pr agar koi intance add kr rhe to vo bhi to sabme apply hoga plus hm log bdd me dono ko hoi change kr skte h, to difference hi ky h dono me??????????????????????????
Bhaiya apka content sabse badhiya hota hai.
harry bhai practice que bhi bnawo DSA ka.... notepad pepadha dijiy....
Both variables are changing values values for instance then what is the difference between two
Same question, still finding the answer in comments
