Treehouse Moderator 145,860 Points[SOLVED] Any ideas on why I'm getting this error and failure to compile?
Well, only the third video... and I broke it. :(
Any ideas?

I'm still relatively new to Python and PyCharm, so I'm kind of at a loss now for troubleshooting.
Thanks in advance!

Treehouse Moderator 145,860 PointsWell,
After banging my head against the wall a few times, I finally noticed that PyCharm interpreter was, for reasons I'm not sure, using Python 3.5.1. This version will throw that error because of the deprecated use by Apple of OpenSSL.
This is, however, now included in the latest version of Python (3.7) and is why the code runs once this was changed.
I am running on a Mac
Once I went to the Applications and found the Python 3.7 folder, I just double-clicked the Update Shell Command file and like magic, everything now seems to work just like Ken's
I need a Tylenol now! Lol
Hope this helps someone else down the road! :)

P.S. Don't forget to install a parser. For some reason, hmtl-parser didn't work for me, so I used "lxml" instead. Worked like a charm.

23,007 PointsI don't know where I am going, I cannot find the Update Shell Command - I am currently using a Mac - could you explain where you went exactly?

Once you download Python 3.7, there should be a "Python 3.7" folder in your Root Application folder in Finder. Inside that folder there is the
Update Shell Commandcommand file that you just double click on.
