In python you may have a program or some data that you would like to store. You may have a file or bunch of files that you may need to work with. You can read files and write new files with your programs. By saving or linking to files in the same directory or elsewhere you can do this.  https://www.youtube.com/watch?v=Olq86NN6-Ko https://www.youtube.com/watch?v=Uh2ebFW8OYM

UML stands for unified modeling language. It is used to create a blueprint for a project. A use case diagram is a list of steps needed to reach a goal. Its defines what is required and how those requirements are met. You will narrow down what you have to have. Before you create a use case diagram you need to create a description of the use case diagram. For example the above would look something like this: Use case descriptions includes who the actors are, what the triggers are, and other elements. Beta versions of a project have Shall requirements, should requirements can be done but can be done later. A use case diagram uses stereotypes to represent an element of your system. https://whatis.techtarget.com/definition/use-case-diagram https://www.youtube.com/watch?v=OkC7HKtiZC0
