Python static methods, instance methods, class methods

Example method:

Class A:    data = 0    def printd (self):        print (Self.data)

Type (A) #out: Type

a.__dict__ #out:

A = A () #out: {}

Class method: @classmethod

 class   a:data  = def   Printd (self):  
    
     print 
      (self.data)  def   GetData (): A.data  = 1 print   (a.data)  

class A:     = 0    def  printd (self):        print(self.data)    def GetData ():         = 1        print(a.data)   

A = A ()

A.getdata () #out:

Purpose: To write a method that interacts with the class and does not interact with the instance

class A:     = 0    def  printd (self):        print(self.data)    @classmethod     def  GetData (CLS):        = 1        print(cls.data)   

static method:

TODO: Call the static method plus self and do not add self
