[GTALUG] python sweetness — The mysterious case of the Linux Page Table

[R360 Design INC]

Hi, Was wondering if we could squeeze in a question about Python
installation on OS X on this thread:

To set up Python on Mac, we were advised to install the latest version
of Python 3.6.4 and PIP3 (According to the Hitchhiker's Guide to
Python http://docs.python-guide.org/en/latest/starting/install3/osx/)
. The installation folder is:

MacBook-Pro: which python3
/usr/local/bin/python3


However, when we checked the package list, the packages are still
pointed at the Python 2.7 packages folder (the native version of
Python that ships with Mac). Is this correct or we need to re-install
the packages for Python 3.6.4 using PIP3?

MacBook-Pro:bin owner$ pip3 show pandas
