A word of advice: don't use a "bare" except, i.e. one that doesn't
specify what exception(s) it should catch.
In another case where I had a "bare exception", I was using it to see if
something was defined and substitute a default value if it wasn't. Have
I cleaned this up properly?
try
id = xmlmodel.attrib['name']
except KeyError:
id = "constant power"
Never mind! After I continued testing, I realized that the above
should have been written as:
if 'name' in xmlmodel.attrib:
id = xmlmodel.attrib['name']
else:
id = "constant power"
<facepalm>
That's actually _less_ Pythonic.
Have a look at the entries "EAFP" and "LBYL" here:
