self and init in python
class Computer:
def __init__(self):
self.name= ("Pankaj")
self.age= 28
c1=Computer()
c2=Computer()
c1.name= "Garg"
print(c1.name)
print(c2.name)self and init in python

The __init__ function serves two main purposes.
The first is its used as a tool to pass
arguments inside of it but the difference is you can spread those
arguments to other functions located in the same class.
To do this you would place the word (self.) keyword in another function
followed by the arguments name. This allows the argument to be spread
down to that function.
The second purpose is it allows you to pass arguments to a
class when calling the class. Without this function inside the class
when you call the class no arguments would be able to go inside getting
nothing in return.python init

def __init__(self, name):
self.name = namewhat is __init__ in python
# If you are familiar with C++ or Java think of the __init__ method as a constructor.
# It is the method that is being called when the class is called.In the following
# example we will see how we can call the __init__ method
