Does not seem to be working, when I run this with Python 3 I get the below:

File "/usr/share/doc/python3-pifacedigitalio/examples/valve.py", line 19
print a['value']
^
SyntaxError: invalid syntax

(not sure if this wil lmess up the alignment, in console that carat points at the letter 'a')

If I run this as Python2/Python I get this:

ImportError: No module named ubidots
