Not sure what other Python devs at 18F do, but I installed Python 2 and Python 3 on my laptop. I find it handy to default to 3 with an option to point new virtualenvs to Python2 in specific cases.

Strong recommendation for using pyenv to manage multiple versions, rather than system installation. It keeps your system dependencies separate from development dependencies, eliminates the need for sudo to manage language use, and plays nicely with virtualenv and virtualenvwrapper.

I have python 2 & 3 installed via homebrew and haven't had to manage anything with sudo. You can specify a specific Python version when running mkvirtualenv, and that seems to be working.

That said, if pyenv makes it easier to manage Python 2/3 with no drama when working with virtualenvwrapper, that would be swell.

I don't have a strong opinion on this since I'm new to Python, but if Homebrew works, then that seems to be the easiest option and wouldn't require installing an additional tool. But I'd like to hear from more Python users. @jackiekazil, @kaitlin, @khandelwal @cmc333333 ?

I know @seanherron's had some experience, as well.

For me, pyenv is way overkill and a solution in search of a problem. I use brew to install py2 and py3 and similar to @bsweger, I default to py3 most of the time.

The people have spoken. I will install py3 via brew in the default script.

Add python3 and virtualenvwrapper.

Since `virtualenvwrapper` requires sourcing before the `mkvirtualenv` command can be used, this now makes 2 commands that need to be sourced after the script ends. RVM is the other one.

Instead of adding another command to the `bash mac` script, I've opted to quit Terminal after the script ends. That way, when Terminal is relaunched, everything will be working.

Closes #2 and #3.

Instead of making the installation command even longer, I've opted to add
instructions to quit and relaunch Terminal after the script ends.
