Python staticmethod()
The staticmethod() is a built-in python function that returns a static method of a given function.
The Python staticmethod() function is a built-in function that transforms a regular function defined inside a class into a static method. It takes a single parameter: the function to be converted. A static method does not receive an implicit first argument (neither self for instances nor cls for the class), which means it behaves like a plain function that happens to live inside a class’s namespace. The function returns a static method object. In modern Python, the preferred approach is to use the @staticmethod decorator instead of calling staticmethod() directly. Static methods are useful for grouping utility functions that are logically related to a class but do not need access to instance or class state. A real-world example is a MathHelper class containing methods like is_prime() or celsius_to_fahrenheit() that perform calculations without depending on any object data. Compare this with classmethod(), which receives the class as its first argument.
What does staticmethod() return?
The staticmethod() function returns a static method object that wraps the given function, allowing it to be called on the class without instantiation and without receiving any implicit arguments.
When should you use staticmethod()?
Use staticmethod() (or the @staticmethod decorator) when you have a utility function that belongs logically inside a class but does not need access to the instance (self) or the class (cls).
The syntax of staticmethod() is:
1
2
staticmethod(function)
staticmethod() Parameters
The staticmethod() takes only one argument as parameters:
- function - Name of the function that needs to be converted to a sciatic method.

return x + y
# create addNumbers static method
Mathematics.addNumbers = staticmethod(Mathematics.addNumbers)
print('The sum is:', Mathematics.addNumbers(5, 10))
Output:

The sum is: 15
Common Use Cases
A common use case for staticmethod() is defining validation or conversion helpers inside a class, such as a User.is_valid_email(email) method that checks email format without needing any user instance data. Another practical scenario is grouping related mathematical or string utility functions under a class namespace for better code organization. It is also useful in factory patterns where a static method serves as an alternative constructor that does not need class-level configuration, distinguishing it from a classmethod() which would receive the class itself.
