Illustrate three operations for:

string manipulation $($e$.$g$.,$ count the number of characters, replacing characters, etc.$)$

lists $($e$.$g$.,$ slicing, adding an element, removing an element, etc.$)$

dictionaries $($e$.$g$.,$ creating a dictionary, update a value, etc.$)$

sets $($e$.$g$.,$ union, intersection, difference, etc.$)$

So$,$ in total $12$ operations. And each operation is worth $10$ pts

Be creative in the illustrations. You can choose the data that you would like. To help you get started, look at the Jupyter Notebooks of the $2$nd week, where several operations using data on US presidents are demonstrated. Please, use different data $($e$.$g$.,$ countries, US senators$,$ companies, etc.$).$ You can also create your own data.
