pythondev | help | anyone here well versed in yapf? I’ve just switched to it from autopep8 and I want to enforce a certain behavior.
In one instance, I have this:
```candidates = Channel.select().where((Channel.name**'HowToPronounce%') | (Channel.name**'Pronunciation%'))```
and yapf formats it the way I want:
``` candidates = Channel.select().where(
(Channel.name**'HowToPronounce%') | (Channel.name**'Pronunciation%')
)
```
later in the same file, I have
```videos_to_evaluate = YoutubeVideo.select().where((YoutubeVideo.views < 10000) & (YoutubeVideo.interesting == None))```
but it formats it as
```
videos_to_evaluate = YoutubeVideo.select(
).where((YoutubeVideo.views < 10000) & (YoutubeVideo.interesting == None))
```
Is there a way to make it always format like the former, where a method call with no parameters doesn’t get split? | 2019-03-13T09:50:07.420600 | Carrol | pythondev_help_Carrol_2019-03-13T09:50:07.420600 | 1,552,470,607.4206 | 13,124 |

pythondev | help | HI, I'm confused! When i create a custom class that inherites from Exception, then i extend this class with subclasses, how does Python reverse the lookup to the base class?
```
class ParentError(Exception):
message("parent msg")
class ChildError(Parent):
message(" child msg")
# raise an error somewhere:
raise ChildError()
# then somewhere catch the Child error via the Parent:
try:
except Parent as err:
. # catches ChildError() ...? ``` | 2019-03-13T17:54:22.490100 | Tasha | pythondev_help_Tasha_2019-03-13T17:54:22.490100 | 1,552,499,662.4901 | 13,209 |
