Python script to web page

I’ve done some research about turning a python script that I have written into an HTML web page. My experience with HTML is somewhat limited, but from what I can tell, I would have an HTML file, and would incorporate Django into said HTML file.

Is it as simple as putting something in the HTML file like

<p> The function call is: <> myFunctionCall() </><>

Or is there a lot more to it than that?
