Pablo: PyStack is my single go-to debugging tool whenever something gets stuck or doesn't do what I'm expecting it to do when I run a Python command at a command prompt. It's as easy as pip install Pystack. Find something that isn't working the way you expected to. Point Py Stack at it and see if you can figure it out. And of course, we're open to contribution. If you find especially issues, if you find something that's broken, let us know.
