An exercise to help build the right mental model for Python data. The “Solution” link uses memory_graph to visualize execution and reveals what’s actually happening:
- Well on one hand, I guessed correctly. (I’m not super familiar with Python) - On the other hand, that solution site is not exactly mobile friendly. - You are right, in landscape mode it’s better, but still not ideal. It’s a project I don’t have time for now. On the other hand, did you run Python code, in an IDE where the debugger visualizes the whole program state, on your Phone before? 
 
- Why can’t it just return the result but has to use the same names in both scopes, I hate it - It’s a nice exercise and a cool visualization though - The whole point is to practice Python Data Model concepts, it’s not a best-way-to-code example, so feel free to hate. 
 
- It’s D - Nice one. 
 
- My guess- It’s C. And if that’s wrong, it has to be D. There is no way it’s A or B - C is incorrect,sorry. See the “Solution” link for the correct answer.
