classmethod() to get method for the function in Python

We can use the class and its properties inside that method rather than a particular instance

classmethod has a reference to a class object as the first parameter. ( staticmethod has no reference )

Example:

class animals():
    def __init__(self,name,height):
        self.name= name
        self.height=height
    @classmethod
    def legs(cls):
        print("has four legs") 
#animals.legs=classmethod(animals.legs)
animals.legs()

Output

has four legs

or create a class method like this

animals.legs=classmethod(animals.legs)
animals.legs()

Class methods are useful when you need to have methods that aren’t specific to any particular instance, but still involve the class in some way

class animals():
    home='Jungle'
    def __init__(self,name,height):
        self.name= name
        self.height=height
    @classmethod
    def legs(cls):
        print("has four legs: stays in ",cls.home) 
animals.legs()

Output

has four legs: stays in  Jungle

In staticmethod() we are not going to pass any instance of class to it.
staticmethod()

Using isinstance()

By using isinstance() we can check if the object is instance of the class or not.
