Similarities and differences of Staticmethod and Classmethod in Python

Class Methodtest ():
var1 = "Class var"
 
def__init__ (self, var2 = "Object var" ):
self.var2 = var2
 
@staticmethod

Defstaticfun ( ):
print ' static method '
 
@classmethod

Defclassfun (CLS):
print ' class method '

The same points as Staticmethod and Classmethod:

1. Can be called from a class or instance

MT = Methodtest ()

Methodtest.staticfun ()

Mt.staticfun ()

Methodtest.classfun ()

Mt.classfun ()

2. Cannot access instance members

@staticmethod

Defstaticfun ( ):
print var2 c19> //wrong
@classmethod

Defclassfun (CLS):
print var2 //wrong

The difference between Staticmethod and Classmethod:

1.staticmethod without parameters, Classmethod requires class variables to be passed as arguments (not an instance of the class)

Defclassfun (CLS):
print ' class method '//cls passed as a class variable

2.classmethod can access class members, Staticmethod can not

@staticmethod

Defstaticfun ( ):
print var1 c30> //wrong
@classmethod

Defclassfun (CLS):
print cls.var1 //right
