Installation instructions for Ubuntu Linux

Installing IDLE

Recent versions of Ubuntu Linux (e.g., Ubuntu 14.04) already have Python 3 installed. IDLE, however, the program we will use to write and execute our Python programs, is not installed by default.

  1. Click or tap the Dash button in the Launcher. (This button is usually the top left corner of the screen.)
  2. Type “terminal” in the search text field and click the Terminal application.
  3. At the terminal, type

    sudo apt-get install idle3
  4. You will be prompted for your password. You won’t see any asterisks or dots as you enter it; this is for your security.

  5. If prompted, type y for “yes” to allow the installation to continue.
  6. When the installation is complete, you can close the Terminal application.
  7. An IDLE icon should be visible in the Launcher or accessible by searching.
