Notes and experiences for yesterday and today. I ‘wasted’ a lot of time, again, struggling with exercises yesterday and ended up being too zombied to even write the summary post. Have been much smarter about it today. Stopped after about 30 mins and copied and tried to understand the solution.

If I find myself using lots of functions, just to deal with these structures, I am better off using classes. These structures also lend themselves to being converted into classes. Sometimes it’s just a matter of adding a few methods, et voilà, I have a class! Lists of lists ...

Started with a new Reuven Lerner Course, on Advanced Data Structures.. Aiming to comfortably finish this in a week. Notes and experiences, follow. The course is three parts. Part 1 - Deep dive into the common data structures Part 2 - Combining Data Structures. Lists of lists, Dicts of lists, Tuples of Lists and so forth. How far can I go without classes? Or how can I enhance my classes with this approach? Part 3 - Complex data structures, that come with the Python Standard Library. The Collections module, Weak references etc. Notes Part 1 ...
