Installing Python

Python is a popular language for research computing, and great for general-purpose programming as well. Installing all of its research packages individually can be a bit difficult, so we recommend Anaconda, an all-in-one installer. Regardless of how you choose to install it, please make sure you install Python version 3.x (e.g., 3.4 is fine). We will teach Python using the Jupyter Notebook, a programming environment that runs in a web browser. For this to work you will need a reasonably up-to-date browser. The current versions of the Chrome, Safari and Firefox browsers are all supported (some older browsers, including Internet Explorer version 9 and below, are not).

Windows

Video tutorial

  1. Open https://www.anaconda.com/download/ with your web browser.
  2. Download the Python 3 installer for Windows.
  3. Install Python 3 using all of the defaults for installation except make sure to check that the Anaconda distribution is the default Python.

Mac OSX

Video tutorial

  1. Open https://www.anaconda.com/download/ with your web browser.
  2. Download the Python 3 installer for OS X.
  3. Install Python 3 using all of the defaults for installation.
    • If ypou want to install Anaconda in your home directory ("for me onluy"), and the respective dialog when it initially appears prohibits this choice, change the location to system-wide ("for every user"), and then change it back. (This is a bug in the installer that can manifest on some versions of MacOSX.)

Linux

  1. Open https://www.anaconda.com/download/ with your web browser.

  2. Download the Python 3 installer for Linux.

  3. Install Python 3 using all of the defaults for installation. (Installation requires using the shell. If you aren't comfortable doing the installation yourself stop here and request help at the workshop.)

  4. Open a terminal window.

  5. Type:

    bash Anaconda3-

    and then press tab. The name of the file you just downloaded should appear.

  6. Press enter. You will follow the text-only prompts. When there is a colon at the bottom of the screen press the down arrow to move down through the text. Type yes and press enter to approve the license. Press enter to approve the default location for the files. Type yes and press enter to prepend Anaconda to your PATH (this makes the Anaconda distribution the default Python).

To confirm successful installation

  1. Open a Terminal or command prompt

  2. Type

    jupyter notebook

    and the default web browser should load and display the Jupyter dashboard.
