Setting up Windows for Python and this class¶
NOTE: this is from memory: no system to test on right now.
Getting The Tools¶
There are a number of python distributions available – many designed for easier support of scientific programming:
Anaconda Enthought Canopy Python(x,y)
But for core use, the installer from python.org is the way to go:
You want the installer for Python 2.7.8 – probably 64 bit, though if you have a 32 bit sytem, you can get that. There is essentially no difference for the purposes of this course.
Double click and install.
You can use the “DOS Box” as a terminal, though the newer “powershell” is a better option.
But to use the Python in the terminal efectively, you need to put a couple paths on your “PATH” environment variable:
You want to add:
Get a git client – the gitHub GUI client may be nice – I honestly don’t know.
There is also ToroiseGit:
which integrates git with the filemanager. But for the purposes of learning, it may be better to use a command line client:
I think that gives you a “Git bash shell” – a command window that gives you a *nix - like command line shell.
pip is the Python package installer. Unfortunately, it doesn’t come out of the box with Python2.7, so you need to install it:
download get-pip.py from that site, and run it with python:
$ python get-pip.py
It should download and install pip (and setuptools)
You can now use pip to install other packages.
One we are going to use in class is iPython:
$ pip install ipython
You should now be able to run iPython:
$ ipython Python 2.7.8 (v2.7.8:ee879c0ffa11, Jun 29 2014, 21:07:35) Type "copyright", "credits" or "license" for more information.
