Static methods in Python?

Question

Is it possible to have static methods in Python so I can call them without initializing a class, like: ClassName.StaticMethod ( )

Answer 1

Yes, Python does support static methods and you can call them without creating an instance of the class. For example:

ClassName.static_method()

And you accomplish this using the @staticmethod decorator. An example of a static method in Python is:

class MathUtils:

@staticmethod

def add(a, b):

return a + b

# call without creating an object

result = MathUtils.add(3, 5)

print(result) # Output: 8

In this example above, no object was created and it was called directly from the class. So, you can always call these static methods by saying ClassName.method() which allows you to do it without the need to create an object.

Answer 2

Yes, and it is quite simple.

class C(object):

@staticmethod

def fun(arg1, arg2, ...):

...

As you can see by this example (from https://www.geeksforgeeks.org/class-method-vs-static-method-python/), all you need is to add the @staticmethod decorator.

Additionally there is an older way to do this.

class Mathematics:

def addNumbers(x,y):

return x + y

#create addNumbers static method

Mathematics.addNumbers = staticmethod(Mathematics.addNumbers)

print('The sum is:', Mathematics.addNumbers(5,10))

As you can see, a function (addNumbers()) is created and then extablished as a static method by line 7 (The line below the comment).
