Time for action – installing Python on different operating systems


NumPy has binary installers for Windows, various Linux distributions, and Mac OS X at http://sourceforge.net/projects/numpy/files/. There is also a source distribution, if you prefer that. You need to have Python 2.4.x or above installed on your system. We will go through the various steps required to install Python on the following operating systems:

  • Debian and Ubuntu: Python might already be installed on Debian and Ubuntu, but the development headers are usually not. On Debian and Ubuntu, install the python and python-dev packages with the following commands:

    $ [sudo] apt-get install python
    $ [sudo] apt-get install python-dev
    
  • Windows: The Windows Python installer is available at https://www.python.org/downloads/. On this website, we can also find installers for Mac OS X and source archives for Linux, UNIX, and Mac OS X.

  • Mac: Python comes preinstalled on Mac OS X. We can also get Python through MacPorts, Fink, Homebrew, or similar projects.

    Install, for instance, the Python 2.7 port by running the following command:

    $ [sudo] port install python27
    

    Linear Algebra PACKage (LAPACK) does not need to be present but, if it is, NumPy will detect it and use it during the installation phase. It is recommended that you install LAPACK for serious numerical analysis as it has useful numerical linear algebra functionality.

What just happened?

We installed Python on Debian, Ubuntu, Windows, and the Mac OS X.
