Python staticmethod() | Python @staticmethod

Static method belongs to a class and not to an object. It does not take self and cls as a parameter. Static method cannot access instance variables and instance methods of a class. Static methods work like regular functions. And mainly used as utility functions. Outside the class, static methods can be accessed using objects and classname as shown below-

obj.methodName()
OR
ClassName.methodName()

There are two ways of creating static methods-

1. Using @staticmethod decorator
2. Using staticmethod() method

How to create static method using @staticmethod decorator?

It is the most preferred way of creating static methods. It has the following syntax-

@staticmethod
def functionName(arg1, arg2, ...):
  #function body

Python program to create static method using @staticmethod

class Math:

  @staticmethod
  def add(p1, p2):
    return p1+p2

print('Sum of 23 and 54 is', Math.add(23, 54))

Output of the above program

Sum of 23 and 54 is 77

Note: Using the below syntax, you can call other class and static methods from class method-

cls.MethodName()
OR
ClassName.MethodName()

How to create static method using staticmethod() method?

staticmethod() is used to convert a regular method to a static method.

class Math:

  def add(p1, p2):
    return p1+p2

#creating add static method
Math.add = staticmethod(Math.add)
print('Sum of 23 and 54 is', Math.add(23, 54))

Output of the above program

Sum of 23 and 54 is 77
