Change subject: [IMPR] Add explicit return value for _query_continue and _continue ...................................................................... [IMPR] Add explicit return value for _query_continue and _continue - Add explicit return value for thes QueryGenerator methods. _query_continue and _continue are called in line 2889 and expects a boolean result; the function is assigned in 2471 and 2474. But only _query_continue returns True only for one part of processing. All other cases return implicit None but an explicit False should be returned instead. - return None in Request._simulate as last resort - Futhermore remove PY2 related code Change-Id: I36340e56ab18a7e78202bc8a314fca9f8958c353 --- M pywikibot/data/api.py 1 file changed, 70 insertions(+), 112 deletions(-) Approvals: Zhuyifei1999: Looks good to me, approved jenkins-bot: Verified diff --git a/pywikibot/data/api.py b/pywikibot/data/api.py index 4b421dc..217fc51 100644 --- a/pywikibot/data/api.py +++ b/pywikibot/data/api.py @@ -5,28 +5,24 @@ # # Distributed under the terms of the MIT license. # -from __future__ import absolute_import, division, unicode_literals -
