Am I using static method correctly?

Question

I have a large class that looks like the following:

class Trainer:
    def __init__(self, name, age, height, weight):
        self.name = name
        self.age = age
        self.height = height
        self.weight = weight
    
    def fit(self, dataloader):
        ....DO MODEL TRAINING...
        
        self.save(path=xxx)
        self.load(path=xxx)
    
    def save(self, path):
        self.model.eval()
        torch.save(self.model.state_dict(), path)
    
    @staticmethod
    def load(path: str):
        """Load a model checkpoint from the given path."""
        checkpoint = torch.load(path, map_location=torch.device("cpu"))
        return checkpoint

From here, I see that since my load() does not need self since in the load method, we do not call self, then we should use staticmethod. Is this correct?

Yes you can use static method here. To use static method we don't need to pass class instance, self argument to work upon. Static methods are like , they are just independent of class's instance. And they can be called directly via Class_name.static_method_name without creating the instance to access the method.
