import unittest import inspect ### OOP #1 ### The file name should be renamed to your Student ID (00XXXXXXX_hw4.py) ### Each question in section 1 is worth 10 points. ### Each question in section 2 is worth 20 points. ### Your programs should pass the provided test cases. ### When you want to test your program, uncomment the appropriate test case from bottom, run the program. ### Depending on the test results, modify the code or move to the next question. ### The questions are separate, and the earlier results do not affect your ability to complete other question. ### Do not modify the structure of the code. ### Start of HW4 # Classes class Test: def __init__(self): self.some_value = 42 def change_value(self, new_value): self.some_value = new_value def add_to_value(self, numb):
