Please follow these steps carefully and in order.

1) Uninstall Other Pythons

If you have other versions of Python installed on your computer and you don't have a compelling reason to keep them around, we recommend uninstalling those versions of Python before continuing on with these instructions.

2) Download the software:

Download the following file to your Downloads folder: Python 3.6 Installer

3) Install the Python Interpreter

Double click on the Python installer to begin the Python installation process, and follow the following steps carefully:

  1. On the first page, check the box labeled "Add Python 3.6 to the PATH", and click "Customize Installation".
  2. On the following page, make sure all boxes are checked, and click "Next".
  3. On the following page, check the box labeled "Install for all users".
  4. On that same page, change the text in the box under "Customize install location" to that it reads: C:\Python36
  5. Click "Install".
  6. Wait for the installation to finish and click "finish". Note that installing Python will also automatically install IDLE.

4) Test

You can test that the installation worked by running python from a DOS prompt (open the start menu, search for cmd, and run it). Python should report its version as 3.6.x, where x is a small integer. You can then type exit() to quit, or simply close the terminal window.
