Initialize the values of properties

what does this mean:

Note that you do not initialize the values of properties, the Python code will not compile . Initializing the values of properties inside the class is necessary.

if we have a class named class test:

if we do test_obj = test() does this mean initialization?

Type your question above this line.


I think I know, it was in the second tab, basically it has not assign to any variable or numbers
