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.
- 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.
- 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.
exit()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
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
sudo easy_install distribute pip
sudo pip install pyreadline ipython tornado pyzmq ipython-notebook ipython_doctester
Verify that IPython Notebook is ready by typing
Your browser should come up with a tab reading "IP[y]:Notebook".
You have tested your Python installation.
