Subject: [code-quality] pylint, enums, and redefined-variable-type
Message-ID: <CY1PR08MB1333D2F592B00B54836664CDE2C90@CY1PR08MB1333.namprd08.prod.outlook.com>

Hello,

I'm using python 3.4.2 and pylint 1.5.2. Pylint is printing a r:redefined-variable-type warning when I use a variable of type enum. The following script demonstrates the problem:

from enum import Enum

class MyEnum(Enum):
    Value1 = 1
Value2 = 2

myEnum = MyEnum.Value1
print("my enum is {}".format(myEnum))

# Huh? this line generates
# warning R0204: Redefinition of myEnum type from EnumRepro.MyEnum.Value1 to
# EnumRepro.MyEnum.Value2 [R:redefined-variable-type]
myEnum = MyEnum.Value2 # this generates
print("my enum is {}".format(myEnum))

Is this expected? At the moment I'm just disabling R0204 at the code locations that produce the problem ... I'm new to python, so perhaps I'm just doing something dim.

Thanks!
Eli

Hey Eli,

* Tayrien, Eli (HBO) <Eli.Tayrien at hbo.com> [2016-01-11 18:26:20 +0000]:
> class MyEnum(Enum):
>     Value1 = 1
> Value2 = 2

As an aside: As many mail clients like to mess up the indentation when
sending, it's best to use a pastebin or attach a script (if the
mailinglist allows attachments) instead of posting it inline.

> # Huh? this line generates
> # warning R0204: Redefinition of myEnum type from EnumRepro.MyEnum.Value1 to
> # EnumRepro.MyEnum.Value2 [R:redefined-variable-type]

That smells like a pylint bug. I'm guessing astroid (the analysis
library behind pylint) or pylint need to handle enums in some special
way.

FWIW, I also can reproduce it with astroid/pylint from the git
repository.

I suggest you open an issue at [1] and mention @lmedioni as she added
that checker and is probably most familiar with it.

Thanks!

Florian

Contrariwise, it's not a good idea to post a link to your code. The code
should be in the same thread of discussion, available to anyone who
later reads that thread. This should not depend on the availability of
some ephemeral pastebin item.

Instead, post the code inline; but always compose messages as ?plain
text? to avoid too-clever software messing with your program code.

Message-ID: <CAN-Kwu3iTFA=HRn5tNp3sxSa_W35K8dymKbaFr+HpuP-MftbJQ@mail.gmail.com>

Hey all,

I purchased pycqa.org ~30 minutes ago and set up flake8.pycqa.org and
pydocstyle.pycqa.org as tests. Both redirect to the project
documentation for those projects. As other PyCQA projects join and
existing projects decide they'd like a nifty subdomain, we'll be
expanding our usage of the domain.

Also, if anyone wants to help out in building a website for pycqa.org,
I would love to collaborate with you. For the moment, I'm imagining a
static website hosted on GitLab Pages (or if those don't work out,
GitHub pages).

Cheers,
Ian

Awesome! Thanks Ian.

Related question I?ve thought about whether we could come up with an avatar for the PyCQA organization, rather then using the default Space Invaders -esque default on GitHub: https://github.com/pycqa <https://github.com/pycqa>

I would love that. If anyone can come up with one, that would be awesome. I
would also happily make a tonne of stickers for PyCon this year. ;)
