rss_to_json script fails on free events

[hacksburg-john]

The rss_to_json script uses a regex query to extract event info from meetup rss strings: https://github.com/Hacksburg/hacksburg.github.io/blob/master/rss_to_json.ipynb?short_path=6c08775#L41

If the rss string is missing a "Price: " field (which is common for free events) the regex doesn't match and the script fails to run. It can be temporarily bypassed by adding a fake price field to the RSS.

Example string with price:

Details will be given for the operation of the Hacksburg CNC gantry router, generously donated by Onefinity and Torc Robotics, and we will show the machining of a demo part. Feel free to attend only this first part.</p> <p>If you intend on getting CNC trained as a Hacksburg member, we will schedule a time to hold Part 2, where I will teach the CAM programming on the computer and give you remote access to our CAM computer. You will then receive a homework assignment, in the form of a STEP file that you will generate a machining plan and gcode for. You will then execute the plan, with me or another Hacksburg member, to confirm your ability to do CAM programming and CNC machining.</p> <p>This class is for attendees age 16 and up. The class is free for Hacksburg members and $5 for non-members. If you are bringing an attendee under 18, you (the parent/guardian) must stay for the entire duration of the class and approve all shop tool use.</p> </p> <p>Blacksburg, VA  24060 - USA</p> <p>Sunday, August 27 at 1:00 PM</p> <p>1</p> <p>Price: 5.00 USD</p> <p>https://www.meetup.com/hacksburgva/events/295114339/</p>

Example string without price:

I've rejiggered the regex so that the price capture group is None when the Price field is absent. Am I correct in thinking you'll handle rendering of Nones and prices of 0 or less in the caller?
