如何在 Windows 上默认将 Python 3.8 切换到 Python 3.6？

Question

I got two versions of Python on Windows, and try to set Python 3.6 as default. Does anyone know how can I set it? Many thanks!

Answer 1

This is most likely due to the path variable. You can see this in a command window by typing

Path

at your prompt.

To update the settings,

Open the 'System' properties. System Properties

Open Environment Variables Path Variables

Highlight the 'Path' Variable and click edit. Edit Path Variable

Edit the values for the Python entries, to point to the desired python version. enter image description here

OK on all boxes, close any CMD windows open, and open new one. Python command should now reference the correct location.
