Hi Gazza,
The 'if' statement is on the right hand side of the '=' sign is actually a
ternary operator. Read the expression as :
if obj.get('battery_ok') == 'OK':
pkt['battery'] = 1
else:
pkt['battery']=0
(In python Numeric zero, None or False all evaluate to False, anything else
is true).
C++ has a similar operator ? : operator.
See https://www.python.org/dev/peps/pep-0308/ for the rational. Personally
I find it very confusing to use 'if' for both forms.
Hope this helps. Good luck.
Rob
