Why do we use "@classmethod"?

Question

I get the same results when I define a class method in the following two ways.

1-) Using @classmethod

@classmethod
def somemethod(cls)
Some Codes

2-) Normally

def somemethod()
Some Codes

In both ways I can reach the method using name of the class and I can do same operations using the method. The only difference is that I can call the method via object names when I declare the method in the first way.
I think there should be some significant differences between these two methods. Is it?

Answer 1

Yes ,there are difference between the first way ,he does a reference to class ,in first way the class can be taken in consideration to instantiate the object and second way no.
