Installing Python3.4 and the SciPy stack on CentOS

My Linux experiences are primarily associated with Ubuntu and, until recently, have never had to work with an rpm style distro. I know installing software on either one is generally the same despite the use of different package managers, but there were a few online resources I frequently used in which I could no longer reference.

I want to share the operations I performed to install Python2.7 and Python3.4 on CentOS. CentOS is pre installed with Python2.6 but this version does not include some of the nice features 2.7/3.4 provide. Below are mostly the instructions to install the SciPy stack on 3.4, but they should be able to apply to 2.7 by using the proper version of pip.

I’ve provided the two web links I used at the top under REFERENCES¬†
