Python script won't run from the context menu

Question

Working on the basis of this post (and this follow-up post), I've tried adding a python script (which I've added to the path and so on, so that I can run it from the command line everywhere in the system) to the context menu, but I get a strange error message:

To be clear, I have successfully run this script from the command line (using powershell, in case it matters) in the folder in which I'm trying to run it from the context menu.

For reference, this is the command in the registry:

C:\cmdtools\get_abs.py \"%V\"

I reposted this question to stackoverflow and someone answered it.

tl;dr: the context menu will only run .exe files, so I had to point the command part of the registry entry to python.exe, followed by my script as an argument.
