You make changes preferring (A)

if some condition:
    return this
do that

over (B)

if some condition:
    return this
else:
    do that

I agree, but some authors prefer (B) in some cases. Does our linter check against (B)?

[fchapoton]

thanks for the review. I have made the suggested change and fix. Concerning the removal of else, there is indeed no check in the linter for that. And in principle I would say that both are ok. Sometimes I remove the else because the code becomes shorter, but not systematically.

LGTM.
