Question

I would like to set some vim options in one file in the comments section.

For example, I would like to set this option in one file

set syntax=python 

The file does not have a .py extension and I am not interested in making my vim installation recognise all files with this extension as python files.

I know this can be done because I have seen it, but my googling for this has not yet been fruitful.

You’re wanting a modeline syntax, e.g.

# vim: set syntax=python: 

See: Modeline magic at Vim Wikia for more details.
