Thank you for your response, but what we are trying to do now is find a way for VPL to be able to access a student's files on their directory on a Jupyter server and grade them.
For the time being we log in and download them manually, then submit them to Moodle, but we want the execution of the VPL to get the files automatically so that when a student decides to have their files evaluate, the VPL will get them from Jupyter and grade them. I understand what you explained to me about how there's no easy answer, but I came up with another idea based on what I know works, and I explain it below.
Since I am capable of using wget to do this, I thought if there was a way, with the use of strings and variables, to run a wget that gets the correct files based on the name of the student on Moodle and the name of the student on Jupyter. I would assume these have to match, but is there a line of code that gets the name of the student running the execution which would be stored as a string during the execution itself? This would help in the creation of the file path for wget, which uses variables and strings to construct it in the program.
One last question, I would like to know if and how it's possible for a student to run the VPL's execution without providing their own file manually in Moodle since this would be done automatically by the VPL's execution itself.
