Python can not be run

[ConceptaNjolima]

On Activity 1.12.3.5, the Python code does not have the run button.

relates to several activecode blocks in https://runestone.academy/runestone/books/published/cppds/Introduction/ObjectOrientedProgrammingDefiningClasses.html

To fix, complete the Python code and convert to Python activecode blocks.
