Understanding Static Methods in Python: Definition and Examples

Rumman Ansari July 28, 2024 854 views

Static Method

A method defined inside a class and not bound to either a class or an object is known as Static Method.
Decorating a method using @staticmethod decorator makes it a static method.
Consider the following two examples:
- Example1 defines the method square, outside the class definition of Circle, and uses it inside the class Circle.
- Example2 defines the static method square, inside the class Circle, and uses it.

Static Method - Example

Example 1

def square(x):
        return x**2
class Circle(object):
    def __init__(self, radius):
        self.__radius = radius
    def area(self):
        return 3.14*square(self.__radius)
c1 = Circle(3.9)
print(c1.area())
print(square(10))

Output

47.7594
100

Static Method - Example...

In Example 1, square function is defined outside the class Circle.
It determines square of a number, x.
It can be used outside and also inside the class Circle.
Though existing square function serves the purpose, it is not packaged properly and does not appear as integral part of class Circle.

Static Method - Example...

Example 2

class Circle(object):
    def __init__(self, radius):
        self.__radius = radius
    @staticmethod
    def square(x):
        return x**2
    def area(self):
        return 3.14*self.square(self.__radius)
c1 = Circle(3.9)
print(c1.area())  
print(square(10)) # -> NameError

Output

47.7594
NameError: name 'square' is not defined

Static Method - Example...

Example 2...

In Example 2, the square method is defined inside the class Circle and decorated with staticmethod.
Then it is accessed as self.square.
You can also observe that square method is no longer accessible from outside the class Circle.
However, it is possible to access the static method using Class or the Object as shown below.

print(Circle.square(10)) # -> 100

print(c1.square(10))     # -> 100
