Python staticmethod() built-in function
From the Python 3 documentation
Transform a method into a static method.
Introduction
The @staticmethod decorator transforms a method so that it belongs to a class but does not receive the class or instance as the first argument. This is useful for creating utility functions that have a logical connection to a class but do not depend on class or instance state.
A static method can be called either on the class itself or on an instance.
Example
Here is how you define and call a static method:
class MathHelper:
@staticmethod
def add(x, y):
return x + y
# Call on the class
result1 = MathHelper.add(5, 3)
print(result1)
# Call on an instance
helper = MathHelper()
result2 = helper.add(10, 20)
print(result2)
8
30
A static method does not have access to the class (cls) or the instance (self). It’s essentially a regular function namespaced within the class.
