File Name: change_object_properties.py ```python import simple_class as sc from stylepy import h1, h2, h3, h4, h5, h6

Without creating an object or instance we cannot work/use the class

An object is a memory it has all the features and functions that defined in the class

create an object

def get_length1(bus): return bus.length

bus = sc.Bus() h1(f"Bus length : {bus.length}") bus.length = 10 bus.get_length = get_length1 h2(f"Bus length : {bus.length}") h3(f"bus length is : {bus.get_length(bus)}") bus.additional_param = 9

we can assign and change the properties from out side but it is a bad design

h4(f" bus additional param : {bus.additional_param}")

apple = sc.Fruit()

washing_machine = sc.WashingMachine()```
