How Handled the new function as a subtask and followed the algorithm flow.
Resources Consulted the Q2.py code as a reference and learnt from it and also the Block
3 pdf notes. Run all .py files in nootbook including .txt file
Difficulties It took me while to understand transition from list to dictionary. I was also
struggling to understand logic behind the notebook specialy how to move
things in one folder in order to work with dictionary, csv files.
Lessons
learnt
Break the problem into sub-problems and follow the algorithm flow carefully.
