Static Method in Python

 

Static Method in Python

To define static method, @staticmethod decorator is used, method defined under @staticmethod decorator are static method

 
#program to define static method
 class Employee_data :     @staticmethod
     def operations():
         print("this is static method")

• Static Method perform operation on static variables.

 #program 

 class Employee_data :
     website = "AETies"
     @staticmethod
     def operations():
         print("\nwebsite : ", Employee_data.website)

 Employee_data.operations()              # calling static method with class name

 emp_1 = Employee_data()
 emp_1.operations()                      # calling static method with class name

 #Output

 website :  AETies

 website :  AETies

• Class name can be used to call static method.

 #program

 class Employee_data :
     website = "AETies"
     @staticmethod
     def operations():
         print("\nwebsite : ", Employee_data.website)
         print("this is static method,\noperation on static variables can only be performed by static method,\n"
              "static method gets memory at class loading time,\n"
              "so can directly access by class name without creating object,\n"
              "static method can be access by class name and object\n")

 Employee_data.operations()              # calling static method with class name

 #Output

 website :  AETies
 this is static method,
 operation on static variables can only be performed by static method,
 static method gets memory at class loading time,
 so can directly access by class name without creating object,
 static method can be access by class name and object

• Static method can be called with object as well.

 #program

 class Employee_data :
     website = "AETies"
     @staticmethod
     def operations():
         print("\nwebsite : ", Employee_data.website)
         print("this is static method,\noperation on static variables can only be performed by static method,\n"
             "static method gets memory at class loading time,\n"
             "so can directly access by class name without creating object,\n"
             "static method can be access by class name and object\n")

 emp_1 = Employee_data()
 emp_1.operations()                      # calling static method with object

 #Output

 website :  AETies
 this is static method,
 operation on static variables can only be performed by static method,
 static method gets memory at class loading time,
 so can directly access by class name without creating object,
 static method can be access by class name and object

Static Method can not access "cls"(class method) and "self"(instance method) variables.
