RunBase is a simple, text-based computer program built in Python that acts as a digital stopwatch and leaderboard for racing events. When a race coordinator starts the program, they can register athletes with their names, "dorsal" numbers (i don't know what's the name for it in english, oly in portuguese) , and teams, and then start a live race clock with the press of a button. As runners cross the finish line, the coordinator simply types in their "dorsal" number, and the program instantly calculates their exact finish time and saves everything safely into a standard text file on the computer. Later on, anyone can open the program to look up past races, view the overall leaderboard, split the results to see who won the male or female divisions, or search for a specific runner's place, making it a reliable, crash-proof tool for local sports events. I'm new at coding so the code isn't the best and sometimes i used AI to understand why the code was giving problems.
