Notes
--------

- Lists are one of the basic container data types in Python. They hold other objects so we can work with them as a group
- Lists hold objects one by one in order and objects can be looked up from the list using the numeric index of the object
- It is a very common pattern to create an empty list, then go through some logic in a loop to create the object you want in the list and add it in each run of the loop
- This numeric index is zero-based, so look up the first object by 0, the second object by 1, and so on.
- We can pass a slice to get a group of objects out of the list as a new list or a single integer to get a single object out of the list
- Negative numbers means count from the end of the list, -1 is last object, -2 is second to last object, and so on
- Objects can be added to the list when it is created, but also later on using .append and .insert. Objects can be removed using .pop
- Lab exercise 1 tests list building for loop pattern, 2 tests adding objects to lists, and 3 tests list indexing and slicing
