In pycodestyle 2.1.0, E305 was introduced, which requires two blank
lines after top level declarations, too.
See https://github.com/PyCQA/pycodestyle/issues/400
See also #10689; thanks @stepshal for first mentioning this issue and
initial patches
The problem was in the following code:
class ArteTVPlus7IE(ArteTVBaseIE):
...
@classmethod
def suitable(cls, url):
return False if ArteTVPlaylistIE.suitable(url) else super(ArteTVPlus7IE, cls).suitable(url)
And its sublcasses like ArteTVCinemaIE.
Since in the lazy_extractors.py file ArteTVCinemaIE was not a subclass of ArteTVPlus7IE, super(ArteTVPlus7IE, cls) failed.
To fix it we have to make it a subclass. Since the order of _ALL_CLASSES is arbitrary we must sort them so that the base classes are defined first. We also must add base classes like YoutubeBaseInfoExtractor.
'make lazy-extractors' creates the youtube_dl/extractor/lazy_extractors.py (imported by youtube_dl/extractor/__init__.py), which contains simplified classes that only have the 'suitable' class method and that load the appropiate class with the '__new__' method when a instance is created.
