Please tell me how to execute python file in Ubuntu by double

This thread is getting like a mini hologram of our current surreal time…
If we can put aside who is right and wrong for a moment we see the more 
frightening spectacle that Repubs and democrats, Remainers and Brexiters and so 
on all over — by getting more and more shrill are not talking to each other but 
past each other

So…

So to Rick:

Not if you use something like file (magic)
My (unschooled) estimate is it gets its detection right 80% of the time

And to Chris and others who think file(magic) is a replacement for file-associations. Even assuming that magic works 100% :

Say I have an html file.
That means its ALSO a text file.
So its equally legitimate to set defaults to use…
- a plain text editor (of which there are hundreds)
- to open it in browser of choice (also plural nowadays)
- some sort of html composer
- etc

Which means we are beyond the nature of the file per se to the pattern of its usage

Yeah… magic… in the category of mind-reading? sooth-saying?
