You can use metaclasses to dynamically create and modify classes.

class AutoAttributeMeta(type):
    def __new__(cls, name, bases, dct):
        for attr_name in ["attr1", "attr2", "attr3"]:
            dct[attr_name] = f"Automatically added: {attr_name}"
        return super().__new__(cls, name, bases, dct)

class DynamicClass(metaclass=AutoAttributeMeta):
    pass

print(DynamicClass.attr1)  # Output: Automatically added: attr1
print(DynamicClass.attr2)  # Output: Automatically added: attr2
