Problem statement
You are given a Person class with instance attributes name and age. Implement the function modify_person(name, age, new_name=None, new_age=None) that:
- Creates a Person with the provided name and age.
- If new_name is not None, update the person's name to new_name.
- If new_age is not None, update the person's age to new_age.
- Return a tuple (person.name, person.age) representing the updated state.
This exercise practices creating instances and modifying instance attributes directly.
Task
Create an object from a class and modify its instance attributes directly; return the updated state.
Examples
Input format
Four parameters: name (str), age (int), new_name (str or None), new_age (int or None).
Output format
A tuple (name, age) representing the person's updated attributes.
Constraints
name and new_name are strings; age and new_age are integers or None. Do not print; return the tuple.
Samples
Sample 1
Input
modify_person("Bob", 20, None, 21)
Output
('Bob', 21)
Only the age is updated because new_name is None.
