Python @staticmethod

A static method in Python is a method defined inside a class that does not depend on any instance or class data. It is used when a function logically belongs to a class but does not need access to self or cls. Static methods help organize related utility functions inside a class without creating objects.

This example shows how a static method performs a calculation without creating an object of the class.

Python

class Calc:
    @staticmethod
    def add(a, b):
        return a + b

res = Calc.add(2, 3)
print(res)

Output

Explanation:

@staticmethod makes add() independent of class objects.
Calc.add(2, 3) directly calls the method using the class name.

Syntax

class ClassName:
@staticmethod
def method_name(parameters):
method_body

Parameters:

@staticmethod: Declares the method as static
parameters: Normal function arguments (no self or cls)

Example 1: This example checks whether a number is even using a static method.

Python

class Check:
    @staticmethod
    def is_even(n):
        return n % 2 == 0

print(Check.is_even(10))

Output

True

Explanation: is_even() works independently and does not access any class data.

Example 2: This example converts temperature from Celsius to Fahrenheit.

Python

class Temp:
    @staticmethod
    def to_fahrenheit(c):
        return (c * 9/5) + 32

print(Temp.to_fahrenheit(25))

Output

77.0

Explanation: to_fahrenheit() is a utility function grouped inside the class.

Example 3: This example checks whether a given age represents an adult.

Python

class Person:
    @staticmethod
    def is_adult(age):
        return age >= 18

print(Person.is_adult(16))
print(Person.is_adult(21))

Output

False
True

Explanation: is_adult() does not need object data, so it is defined as static.
