if i want to you a file in the code and the file is stored on the desktop then what to do.
Filepaths can be relative in most languages. It looks like you're using Python, so if you wanted to get a file to use, you just need to upload it to your REPL and then reference it with a
filename.extension is your file with its extension i.e. if I need
work.txt you can reference
./work.txt in your code to grab the file.
