I closed the IDLE window these were on, but the error arrow was pointing
to punctuation in each case, a colon in one case, angle bracket in
another. Sorta seems like IDLE is trying to do something with them and
not taking them as simple plain text. But it's not making hyperlinks, so
I'm not sure how much I care exactly what it's doing.

I didn't try printing them before, but I just did. Got:
SyntaxError: invalid syntax (arrow pointing at the colon)

If I do this in GNOME Terminal 2.30.2, the URL http... is a clickable

I need to get a new power supply in my Linux-capable machine, but for
now I'm stuck with Winblows on a very old PC.
As I've mentioned in other posts on this thread, I'm now thinking that I
need to write a class to do this, and find out how Firefox and url aware
terminals in Linux do it. There must be a way.
