Lists are an example of a data abstraction.

A data abstraction can often contain different types of elements. It also provides a separation between the abstract properties of a data type (integer, boolean, string) and the concrete details of its representation. Basically, it doesn’t matter that the type are different!

Create an empty list. Append the integer 3, a string of “hello” and a boolean of False into the list. Print out each index individually. Now, remove the number 3 and False from the list.

Finally, print out the list again.
