pylint

I have a line like this: filter(lambda x: x == 1, [1, 1, 2]) Pylint is showing a warning: W: 3: Used builtin function 'filter' Why is that? is a list comprehension the recommended method? Of course I can rewrite this like this: [x for x in [1, 1, 2] if x == 1] And I get no warnings, but I was wondering if there's a PEP for this? Pylint often chatters on about stuff it shouldn't. You can disable the warning in a .pylintrc file. This page http://pylint-messages.wikidot.com/messages:w0141 indicates the problem is that filter and map have been superseded by list comprehensions. A line like this in

import sys from PyQt5.QtWidgets import (QApplication, QWidget) app = QApplication(sys.argv) window = QWidget() window.setGeometry(50, 50, 500, 300) window.setWindowTitle('Hello, world') window.show() sys.exit(app.exec_()) I just started to learn pyqt5. I wrote this hello world app, which works. But pylint gives "E0611:No name 'QWidget' in module 'PyQt5.QtWidgets'" and same for QApplication. Is it some kind of bug in pylint? pylint --version No config file found, using default configuration pylint 1.7.2, astroid 1.5.3 Python 3.5.2 (default, Aug 18 2017, 17:48:00) [GCC 5.4.0 20160609] slavugan

For the following code: logger.debug('message: {}'.format('test')) pylint produces the following warning: logging-format-interpolation (W1202): Use % formatting in logging functions and pass the % parameters as arguments Used when a logging statement has a call form of “logging.(format_string.format(format_args...))”. Such calls should use % formatting instead, but leave interpolation to the logging function by passing the parameters as arguments. I know I can turn off this warning, but I'd like to understand it. I assumed using format() is the preferred way to print out statements in Python 3

I would very much like to integrate pylint into the build process for my python projects, but I have run into one show-stopper: One of the error types that I find extremely useful--: E1101: *%s %r has no %r member* --constantly reports errors when using common django fields, for example: E1101:125:get_user_tags: Class 'Tag' has no 'objects' member which is caused by this code: def get_user_tags(username): """ Gets all the tags that username has used. Returns a query set. """ return Tag.objects.filter( ## This line triggers the error. tagownership__users__username__exact=username).distinct() #

Recent versions of pylint allow for suppressing messages with human readable message ids. For example, instead of class MyTest(unittest.TestCase): # pylint: disable=R0904 ... you can specify: class MyTest(unittest.TestCase): # pylint: disable=too-many-public-methods ... This page lists the numeric message ids. However, I'm looking for a complete list of the human readable versions of the message ids. Where can I find that list? sthenault I don't think there exists (yet) such list on the web, though pylint --list-msgs automatically produces one. I've stumbled upon your question, searching for

I am using the following setup MacOS Mojave Python 3.7.1 Visual Studio Code 1.30 Pylint 2.2.2 Django 2.1.4 I want to use linting to make my life a bit easier in visual studio code however, every import i have states "unresolved import". Even on default django imports (i.e. from django.db import models). I presume it is because it is not seeing the virtual environment python files. Everything works just fine but but it's starting to get annoying. The interpreter choices i have are all system versions of python. It does not seem to see my virtual environment python at all (it is not in the same
