Pity if you’ve left this place, you’ve missed the whole party. 
Just to save your time, you can try this :
- open the Folder Options. (in Control Panel, or Tool>Folder Options in win explorer)
- bring up the File Types tab.
- select “Folder” type and click Advanced. Be very careful, don’t mess up with “File Folder” type, it can ruin the actions priority, and you’ll have to fix it only by editing the registry !
- create new action, you can name it “PROMPT to here !” or something similar.
- click Browse, and select the “cmd.exe” in \WINDOWS\system32 as the application used to perform action.
- confirm everything.
Using it :
If you right-click any folder, you should see “PROMPT to here !” on the menu. Click it to open the command prompt and directly bring you to that location, as fast as you blink. Then you can start ppython, make sure to INCLUDE the .py extension.
Have funnn !!
