如何在python3中调用类内部的静态方法？

class MyClass:
    @staticmethod
    def my_static_method(arg1, arg2):
        return arg1 + arg2

result = MyClass.my_static_method(5, 10)
print(result)  # 输出: 15

my_instance = MyClass()
result = my_instance.my_static_method(5, 10)
print(result)  # 输出: 15

class MathOperations:
    @staticmethod
    def add(a, b):
        return a + b

    @staticmethod
    def multiply(a, b):
        return a * b

# 调用静态方法
sum_result = MathOperations.add(3, 4)
product_result = MathOperations.multiply(3, 4)

print(f"Sum: {sum_result}")       # 输出: Sum: 7
print(f"Product: {product_result}") # 输出: Product: 12
