I suppose you know that you can manually select highlight mode in the
menu "View > Highlight Mode" when your file is open.

But if you want that your Python files written in .txt files have
automatically Python highlight mode, I don't know how to do this with a
comment at the top of the file, but if you have control on the files
name, you could name them .py.txt and add a Python MIME type for .py.txt.

In resume, if your files must end by .txt, you could actually end them
by .py.txt and add a MIME type to recognize .py.txt files as Python files.

To do that, put the attached file in the following folder (create it if
it doesn't exist):

/home/YOU/.local/share/mime/packages/

and update MIME type database with the following command:

$ update-mime-database /home/YOU/.local/share/mime
