(Scientific) Python on a new Mac

UPDATE: trying this on a new computer in June of 2017. Failing to get --with-python3 to work, and the python tap seems to be gone.

Sasha just asked about this, and then I realized I was saving a list in my shiny new data repo README at work. I emailed her that list and she suggested a blog post. It was great to be asked this while it was still fresh in my mind.

A few notes:

Everyone told me that the science/math/computing Python libs were happy with Python 3 so seemed like a good time to switch over

I just saw the brew tap command for the first time when I was googling all this.

same for --with-python3and then pip3

Basics:
- brew install postgresql
- brew install python3
- brew tap Homebrew/python
- brew install numpy --with-python3
- brew install matplotlib --with-python3
- brew install scipy --with-python3
- brew install scikit --with-python3
- brew install scikit-learn --with-python3
- brew install leiningen
- pip3 install scikit-learn
- pip3 install pandas
- pip3 install jupyter

Survival Analysis:
- pip3 install lifelines

ggplot and prereqs
- pip3 install patsy
- pip3 install statsmodels
- pip3 install brewer2mpl
- pip3 install ggplot

What other scientific libs should I definitely have?

Am I going to run into any gotchas in Python 3?
