Let’s look at an example: def f(value, key, hash={}): hash[value] = key return hash print(f(‘a’, 1)) print(f(‘b’, 2)) Which you probably expect to output: {‘a’: 1} {‘b’: 2} But actually outputs: {‘a’: 1} {‘a’: 1, ‘b’: 2}
pylintalready detects this as a problem (as of version 1.7). For example, here’s my tuple.py: “””Module docstring to satisfy pylint””” def main(): “””The main function””” thing = 1, print(type(thing)) if __name__ == “__main__”: main() $ pylint tuple.py No config file found, using default configuration ************* Module tuple R: 5, 0: Disallow trailing comma tuple (trailing-comma-tuple) … Read more

It is not true for logger statement because it relies on former “%” format like string to provide lazy interpolation of this string using extra arguments given to the logger call. For instance instead of doing: logger.error(‘oops caused by %s’ % exc) you should do logger.error(‘oops caused by %s’, exc) so the string will only … Read more

This may be done by adding # pylint: disable=some-message,another-one at the desired block level or at the end of the desired line of code. You can use the … Read more
The idea behind this message is for the sake of readability. We expect to find all the attributes an instance may have by reading its __init__ method. You may still want to split initialization into other methods though. In such case, you can simply assign attributes to None (with a bit of documentation) in the … Read more

Summarizing all answers. This is a security measure to not load non-default C extensions. You can white-list specific extension(s). Open user settings and add the following between {}: “python.linting.pylintArgs”: [ “–extension-pkg-whitelist=extensionname” // comma separated ] You can allow to “unsafe load” all extensions. Open user settings and add the following between {}: “python.linting.pylintArgs”: [ “–unsafe-load-any-extension=y” … Read more
There are two options I’m aware of. One, change the PYTHONPATH environment variable to include the directory above your module. Alternatively, edit ~/.pylintrc to include the directory above your module, like this: [MASTER] init-hook=’import sys; sys.path.append(“/path/to/root”)’ (Or in other version of pylint, the init-hook requires you to change [General] to [MASTER]) Both of these options … Read more
