Installation instructions for Windows

Installing Python 3

The Python installation also includes IDLE, the program we will use to write and execute our Python programs.

Warning

You must follow these instructions to install version 3 of Python. If you already have a different Python version installed, you should be able to install this version alongside it. It is very important that you install version 3 — do not install version 2.

  1. Go to the download page for Python 3.
  2. Download the latest version of Python 3 by clicking the appropriate Download button. (At the time these instructions were created, the latest version of Python 3 was Python 3.6.2. If you see a later version number, that’s okay, too. Just make sure to select the button for the version number that begins with Python 3 and not Python 2.)
  3. If prompted to do so, choose to save the file.
  4. Double-click or tap the icon for the downloaded file. This will start up an installer program. If prompted to do so, click Run.
  5. You should be able to use all of the default settings that the installer gives you by just clicking or tapping on the Next button.
  6. Once the installation is complete, click/tap the Finish button. Among other supporting applications, a program named IDLE (Python GUI) should now be installed.

Installing the Java runtime environment

The Java runtime environment is also known as the JRE.

  1. Go to the download page for Java 8.
  2. Find the first table of download links (the one for Java SE Runtime Environment 8u161).
  3. Accept the Oracle Binary Code License Agreement by selecting the Accept License Agreement radio button.
  4. Find the line for Windows x64 Offline and click on the name of the file to the right of the red arrow on that line. (The file name should end with -x64.exe).
  5. If prompted to do so, choose to save the file.
  6. Double-click or tap the icon for the downloaded file. This will start up an installer program. If prompted to do so, click Run.
  7. You should be able to use all of the default settings that the installer gives you.
