Link is working now so Travis failure is unrelated to this PR

[sbesson]

Travis errors seems to be E722 and E741. But I see a lot of open PRs are already suffering from these. For the upcoming 3.2.0 release, we'll want to get this fixed prior to integrating the ongoing work. @will-moore @jburel is there already an open PR or staging branch containing the necessary fixes?

#251 contains flake8 fixes

[sbesson]

Thanks. #251 is currently conflicting and needs some review as far as I can tell so I would not tie the changes to this feature PR. Either the flake fixes need to be open as a standalone PR or we could to cherry-pick the changes here and fix master.
Main concern about 14b7807 is that I am unclear about the dropping of the try/except blocks (14b7807#diff-0a76704154b08eff719dbe89fa944468L233 and 14b7807#diff-0a76704154b08eff719dbe89fa944468L378) and the dropped .getValue() (14b7807#diff-0a76704154b08eff719dbe89fa944468R236) - do these require testing?

[jburel]

Being more explicit in the try/except should have been done from the start in my opinion
I would not have expected the getValue to be removed

[jburel]

I will simply it and only indicate
