Week 15. Understanding subprocess module

First thing I need to do in my functionality test: Make the RADI container available. In order to do that, normally, i would type docker start RADI in my linux console.

But now i need to do that inside a python script.

As I was talking with Jose Maria, he told me one of the previous students needed the same functionality for the unibotics tournaments and maybe I could try to use the subprocess library in Python.

As i didnt knew anything about that library, now i needed to make my own investigations in order to use it correctly.

This module give us the chance to work with process, similarly as I would do in a shell. I found two candidate functiones to do what i needed:

1. subprocess.Popen()
2. subprocess.run()

Both seemed to work well with that I wanted to do, si I picked the subprocess.Popen.

First step complete!
