Learn Python CLASS METHODS in 6 minutes! 🏫

Class methods = Allow operations related to the class itself
Take (cls) as the first parameter, which represents the class itself.
Instance methods = Best for operations on instances of the class (objects)
Static methods = Best for utility functions that do not need access to class data
Class methods = Best for class-level data or require access to the class itself
class Student:
count = 0
total_gpa = 0
def __init__(self, name, gpa):
self.name = name
self.gpa = gpa
Student.count += 1
Student.total_gpa += gpa
#INSTANCE METHOD
def get_info(self):
return f"{self.name} {self.gpa}"
@classmethod
def get_count(cls):
return f"Total # of students: {cls.count}"
@classmethod
def get_average_gpa(cls):
if cls.count == 0:
return 0
else:
return f"Average gpa: {cls.total_gpa / cls.count:.2f}"
student1 = Student("Spongebob", 3.2)
student2 = Student("Patrick", 2.0)
student3 = Student("Sandy", 4.0)
print(Student.get_count())
print(Student.get_average_gpa())

Can u Please make a django tutorial

[@Rizzlers_Edits]

nice video dude your tutorial are always a class

[@Hassnaeerr]

Meilleurs explication ❤❤

[@TheQbbxrxr]

you are so good at explaining! thanks

[@shantanughosh655]

I think the reason class method gets so confusing to understand is because in most of the examples taken, people operate on a class variable. First it is defined, then some operation is performed on it in __init__ or some other instance method, then finally calls @classmethod decorator and performs some operation on that class variable. Reason it is confusing bcoz this can be done using self too. Another example is, calling a class method which creates you an object based on some input...again this can also be done w/o class method. There needs to be some tutorial on internet which explicitly explains the use cases of class methods which can't be done by others

[@Irina.Parvanova]

Thank you so much for explaining it so well! So many people tried to explain it to me without success. I even cried my eyes out...
Every time I watch your videos I understand it perfectly! Thank you, thank you, thank you!

Great content Bro 🎉

[@이유찬-e5y]

never knew the keyword cls even exist lol
thanks for the content!

[@aryyann05]

cls is not a keyword, its just a convention

[@ishmaelnaga8628]

QUESTION:
Can't we say that the @classmethod is kind of "useless" as we can replace the "cls" thing with "Student" (class name) itself.Coz i think Student.count would serve the same purpose right ?

[@goktugmustdie]

i didn't understand the difference between static and class methods completely. can someone enlighten me?

[@menegideon7351]

Dear Bro Code,
Pls can you do a full 12hours course on Django. Also using rest framework for creating endpoints and building backend applications
Am a beginner. I really love your courses and I must admit I like the way you teach bro code
I would be very delighted if you do a full 12hours course on Django and also teach us everything on the backend
I would also appreciate it if you used the same approach you adopted while doing the JavaScript 12hours full course where it was practical and project based.
I am my friends love your series
Pls bro code consider this as a special request from a fellow bro💓🥺
Thanks bro code💓

I wrote this program: task = []
def add():
add_input = input("What do you want to add to your tasks list?: ")
task.append(add_input)
print(task)
def less():
less_input = int(input("Enter the index you want to delete "))
task.pop(lessinput - 1)
print(task)
def view():
print(task)
while True:
choices = input("a.Enter the task you want to add to your list
b.Enter the task you want to deduct to your list
c.View you tasks
d.Stop
Enter the choice you would like: ")
if choices == "a":
add()
elif choices == "b":
less()
elif choices == "c":
view()
elif choices == "d":
print("Byeeeeee!!!")
break
else:
print("INVALID INPUT")
