[AWIPS #FTX-514016]: Python-awips

Hi Jamie,

I have some good news to report to you.  I've been able to successfully 
implement the downloading and processing
of pirep data on our backup edex server.  Tomorrow I plan to make these changes 
on our production edex (the one
you're pointing to) and then you should see the same results.  One thing to 
note is that once I start it
tomorrow, it can only gather data from that point on, so don't expect to see 
any data from today or earlier.

The next thing I wanted to mention quickly was how to access the data through 
python.
If you haven't already, you'll need to install the awips python package, this 
can be done with a pip install:
pip install python-awips

Then you should have the proper python libraries for the DAF.
I wrote a small program which I've attached (pirepAccess.py) that should help 
you get started with what you
want to do.  I added some comments about what I tried to do and you can comment 
out lines if they're not
necessary to you.  Basically the program connects to the edex and prints out 
which data sets are available,
and then uses pireps as its data set.  I eventually print out all the 
turbulence intensity values that are
returned from the pireps objects.

Please let me know if this helps.  Like I said, the production database won't 
be updated until tomorrow 
morning, so this script won't work until that's been done, but I wanted to 
respond to you sooner rather than
later so you knew that progress has been made.  Not all is lost.

Thanks.
