Computer Networks Stations Problem

A simple program created for Computer Networks Course. Its main goal is to give the user a list of exercises that are possible to do on the given stations. It is built using Python 3 and BeautifulSoup library.

Overview

• Web scraping is used to get the information about all exercises (id, description, stations it can be done on) from the provided website.
• Not all exercises on the website are available, so user provides the numbers of available exercises to the exercises.txt file.
• App works in console and is intended to resemble Cisco CLI (use cmd for better UX).
• User communicates with the app using commands.

Project structure

• main.py: Entry point of the application.
• commands.py: Contains code for commands given by user.
• exercise.pu: Defines the Exercise class.
• exercises.txt: Contains the list of available exercises.

Commands descriptions

Current version supports 5 commands that user can type into the console:

• show - takes in station numbers as arguments and returns a list of all the exercises that can be done on at least one of them and their amount. All arguments are separated by a singular space. If no arguments are provided, a list of all available exercises is returned.
• no show - takes in station numbers as arguments and returns a list of exercises that are impossible to be done on any of them and their amount. All arguments are separated by a singular space.
• add - takes in exercise numbers as arguments and adds them to exercises.txt. All arguments are separated by a singular space.
• no add - takes in exercise numbers as arguments and removes them from exercises.txt. All arguments are separated by a singular space.
• shutdown - turns off the app.

Commands examples

• show - the components of each returned exercise are: number, list containing information whether it is possible (1) or not (0) to do it on the given station and a short description.
• no show - components of each returned exercise are the same as in show.
• add
• no add
