Static method in R

To define a static method in a class R, you need to use the @staticmethod decorator followed by the function definition. Here is a simple example:

class R:
    @staticmethod
    def print_hello():
        print("Hello, World!")

In this example, we define a class R with a static method print_hello(). This method doesn't require an instance of the class to be called, you can call it using the class itself, like this:

R.print_hello()

This will execute the print_hello() method and output Hello, World!.

Another example is a static method that calculates the sum of two numbers:

class Calculator:
    @staticmethod
    def add(x, y):
        return x + y

In this example, we define a class Calculator with a static method add(). This method takes two arguments, x and y, and returns their sum. You can call this method using the class itself, like this:

result = Calculator.add(2, 3)
print(result)  # Output: 5

This will execute the add() method with arguments 2 and 3, and output 5.
