Lab is broken and not tracking progress....

The lab doesn't work and doesn't tell you what to remember to use later.

There is a problem with the folder "07_parkml" name that is causing the lab not to be validated, I opened a ticket, and I hope they will fix it.

THIS LAB NEEDS TO BE FIXED!!! THE NOTEBOOK OPENS IN PYTHON 3 THEN THROWS AN ERROR - WHEN YOU TRY TO RERUN YOU GET A SPARK CALL ERROR - THEN YOU CANNOT GET CREDIT FOR A WORKING NOTEBOOK! HAS HAPPENED MULTIPLE TIMES! PLEASE FIX THIS FOR THE SAKE OF EVERYONE ELSE!

Not functional in many commands since python is based on version 2.3 for spark
