First of all, thanks for your plugin.
We use it to teach programming at school in C ++, Pascal, Python.
There are still a lot of questions and we need help.
Perhaps these questions arise not only for us, but also for many other teachers. It would be great to add detailed descriptions to the documentation.
1. It is necessary to check the operation of the program on several files (read numbers or lines from the file and process them). We have learned how to check the program on one file.
2. Random input of numbers into the program and checking its work.
