classmethod VS staticmethod in Python

class Dates:
    def __init__(self, date):
        self.date = date
        
    def getDate(self):
        return self.date

    @staticmethod
    def toDashDate(date):
        return date.replace("/", "-")

date = Dates("15-12-2016")
dateFromDB = "15/12/2016"
dateWithDash = Dates.toDashDate(dateFromDB)

if(date.getDate() == dateWithDash):
    print("Equal")
else:
    print("Unequal") 

@classmethod	@staticmethod
Declares a class method.	Declares a static method.
It can access class attributes, but not the instance attributes.	It cannot access either class attributes or instance attributes.
It can be called using the ClassName.MethodName() or object.MethodName().	It can be called using the ClassName.MethodName() or object.MethodName().
It can be used to declare a factory method that returns objects of the class.	It cannot return an object of the class.

I encourage you to use staticmethod since it makes a less confusing.
