Question

Could someone please help me understand lesson 80.1 of python core ?
I copy pasted the code as it is and it got errors and had like no output i also tried understanding the code line by line but there were things i was unable to get

Answer 1

There it first implemented a single class GameObject and next it is inherited into another class Gabbine. So combine 2 codes into one, and run to see output.
read lesson again for explanations..

first code works fine but accepting infinite inputs..
next code extended version of adding 2 classes to first and a examine function added. you need combine these two. third one is improved class of Gabbine class with added functions of prevoius one...
