Linux ships with Python installed, so the goal of this page is to make sure you can start a terminal and run Python from the command line.

  1. Start up a Terminal. You can find the Terminal application at Applications/Accessories/Terminal, or it may already be on your menu bar.

    This Terminal contains something called a command prompt. This command prompt is another way of navigating your computer and running programs -- just textually instead of graphically. We are going to be running Python and Python scripts from this command prompt.
  2. Test your Python install at the command prompt. Type

    and hit enter. You should see something like

    Python 2.7.1 (r252:60911, Jan 24 2011, 17:44:40) 
    [GCC 4.3.2] on linux2
    Type "help", "copyright", "credits" or "license" for more information.
    • You just started Python! The >>> indicates that you are at a new type of prompt -- a Python prompt. The command prompt let's you navigate your computer and run programs, and the Python prompt lets you write and run Python code interactively.
    • If the Python version number (2.7.1 in the example above) is not a number between 2.4 and 2.7 (ignoring the number after the second dot), tell a staff member.
  3. To exit the Python prompt, type
    and press Enter. This will take you back to the Linux command prompt. You can also use Ctrl+D to exit the Python interpreter.

You might need to install a package called python-tk.

Set up IPython[edit]

At the Terminal window for Debian based Linuxes, type

sudo apt-get install python-setuptools

or for Red Hat based distros (will need root permissions)

yum install python-setuptools

then type

sudo easy_install distribute pip

and, finally,

sudo pip install pyreadline ipython tornado pyzmq ipython-notebook ipython_doctester

Verify that IPython Notebook is ready by typing

ipython notebook

Your browser should come up with a tab reading "IP[y]:Notebook".


You have tested your Python installation.
