What we have here is a failure to communicate :-)

I apologise for ruffling your feathers, but its difficult to judge another 
person's level of knowledge. In someways you're obviously quite knowledgeable 
about Python, but in other ways you're still learning (as we all are!) and I'm 
afraid I may have misjudged exactly what your level of knowledge was. Sorry 
about that.

I'm not suggesting that you print "silly plain text strings" just for the heck 
of it. You've asked how to get a clickable link using Python. There is only one 
way I know of to get a clickable link using Python:

Write out a link as plain text to another application which then interprets the 
plain text as a clickable link.

You *might* be able to get clickable links in Python by writing an entire GUI 
application, using (say) the tkinter library, or one of the third-party
GUI libraries like wxPython, kivy, pyqt, or others, but I haven't a clue
how. But even there, your links will start off as text, which means you will 
still need to surround them with quotes to make them strings.


Aside: you've actually raised a fascinating question. I wonder whether there 
are any programming languages that understand URLs as native data types, so 
that *source code* starting with http:// etc is understood in the same way that 
source code starting with [ is seen as a list or { as a dict?


But back to your problem: short of writing you own GUI application, in which 
case you can do *anything you like*, you can:

- write out a HTML file containing the URLs you want, in <a href= ... </a>
tags, then open the HTML file in a web browser and let the web browser 
interpret the HTML tags as clickable links;


- write out an Excel spreadsheet, using whatever format Excel expects, open
the spreadsheet in Excel, and let Excel interpret the mystery format as a 
clickable link;

- print the URL to the console, and see if the console is smart enough to
interpret it as a clickable link.


I'm sorry that I can't give you a one-sentence answer "just use such-and-such a 
function, that does exactly what you want in a platform-independent manner" :-(
