Installing Pylint for Python 3.4 on Visual Studio Code | System: Windows 10
by Hannah.Miles 22 Aug '18

Hello, My name is Miles. I've been having a difficult time installing pylint for python 3.4 on visual studio code Windows 10 system. I went to Powershell and used the "pip install pylint" command and it keeps stating "Fatal error in launcher: unable to create process using '"" C:\Program Files\Python34\python.exe...'"" I'm also new to Windows OS. Do you all know a better way to go about installing pylint on my system?

Possible bug with checkers.utils.is_subclass_of()
by Caio Carrara 21 Aug '18

21 Aug '18

Hello everyone. I'm getting an error using pylint. Currently in my execution the function `checkers.utils.is_subclass_of()`[1] is raising a `NoneType object has no attribute name` exception. Debugging the issue I could check one of the arguments (nodes) used by this function is `None`. I think the expected behavior would be the function return False when one of the nodes is None. But the problem is in this `if` statement[2]. The check is done using `if not any()` but probably the correct way would be check it using `if not all()` to ensure all nodes is subclass of `astroid.ClassDef`. Could anyone double check it with me? If a patch is necessary I can tackle it. My environment details: pylint 2.1.1 astroid 2.0.3 Python 3.7.0 (default, Aug 8 2018, 09:38:40) [GCC 4.8.5 20150623 (Red Hat 4.8.5-28)] [1] - https://github.com/PyCQA/pylint/blob/master/pylint/checkers/utils.py#L1001 [2] - https://github.com/PyCQA/pylint/blob/master/pylint/checkers/utils.py#L1011 Thanks, -- Caio Carrara Software Engineer, Virt Team Red Hat ccarrara(a)redhat.com

pylint: How to ignore max line length limit for long import statements
by Jiongjiong Li 11 Aug '18

Is there any convenient way to ignore max line length limit for import statements, such as by setting rc file? pylint always report: C0301:Line too long (108/100). But according to Google Style Guide<https://github.com/google/styleguide/blob/gh-pages/pyguide.md#32-line-length>, it's fine to not limit line length for long import statements. Thanks!
