Hi Steve,
You can use `pip3 freeze` to print out the names + version numbers of all currently installed packages...
Don't worry too much about the selenium version. the bug that affects versions 40 and 41 is only an issue when you're running your tests under xvfb, which only happens on the jenkins server that we build in the CI chapter, right at the end of the book... when you get to that chapter, you can switch selenium versions by doing a `pip3 install selenium==2.39`
I'm interested to hear how you get on with the book this time round! particularly what you think about chapters 5 and 6...
