Since you’re iterating over _node_attrs outside of a method, you’re operating on the valuesbeforethe dataclass decorator has a chance to process the class. As a result, instead of getting the default value for _node_attrs, you’re getting the raw field object that ...
We want to dynamically add a multiply method to the class using monkey patching. class Calculator: def add(self, a, b): return a + b # Monkey patching to add a new method def multiply(self, a, b): return a * b Calculator.multiply = multiply # Creating an instance of the modified...

As you’ll learn, Python is dynamically typed (it keeps track of types for you automatically instead of requiring declaration code), but it is also strongly typed (you can only perform on an object operations that are valid for its type). Functionally, the object types in Table 4-1 are ...
