What are the best practices for using static methods in Python?

Static methods are used when you want to define a method that doesn't require access to instance or class variables. Here are some best practices:

1. Use static methods for utility functions that don't modify class or instance state.
2. Keep them simple and focused on a single task.
3. Use descriptive names to indicate their purpose.

Can you give me an example of a static method?

Sure! Here's a simple example:

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

In this example, add is a static method that adds two numbers without needing to access any instance or class variables.

When should I prefer static methods over instance methods?

You should prefer static methods when the method's functionality does not depend on the state of an instance. If the method only needs input parameters and does not modify or access instance variables, a static method is more appropriate.

Are there any downsides to using static methods?

Yes, one downside is that static methods cannot access or modify instance-specific data. This can lead to code that is less flexible if you later need to incorporate instance data.
