  1. Visit python.org.

  2. Select Downloads>Windows. If you are not using Windows select your appropriate operating system.

  3. Find the release you are want by scrolling through the Stable Releases. Note: Releases (also known as versions) of Python follow the major.minor.micro convention. More information on Python versioning can be found here.

  4. Once you have found the version you want. Select the appropriate installer. For modern computers with a Windows operating system this will be Windows x86-64 executable installer.

  5. Download the installer and save it to your Downloads directory.

  6. Run the installer, by double clicking the downloaded installer. Important: Be sure to check the Add Python to Path box on the first page of the installer. This will ensure that the Python version you are installing will be findable through the terminal.

  7. Follow the installer instructions.

  8. Check Python installed correctly by opening a terminal, either Windows Powershell (recommended) or Command Prompt on a Windows machine, and enter python --version you should see the name of the Python version that you selected in step 4. For example, if you downloaded Python 3.7.5 you should see Python 3.7.5 printed to the console. Note: If you do not see the correct version number or you get an error that the program python cannot be found, this means that either the installation was not successful or that Python was not added to the path, refer to step 6. If this is the case uninstall the software and repeat the above steps, paying special attention to follow all of the directions.

  9. Enjoy!
