Python virtual environments

My view is that if you want to use virtualenvs in workshops (I would suggest giving them a container or vm instead), just have the virtualenv on when they log in. You can provide a flyer on setting up virtualenvs if you think that's necessary information to read when they try to use the skills.

Personally I've found virtualenvs to be so fragile that I will never use them again. I would advise teaching students a path that doesn't fall over so easily
