How do I disable pylint unused import error messages in vs code

by

As others have said, you can provide a disable argument to disable a specific message. I wanted to elaborate on that. Here is the syntax for disabling multiple messages and for providing multiple arguments, which was not immediately obvious to me from googling it: “python.linting.pylintArgs”: [ “–max-line-length=80”, “–disable=W0142,W0403,W0613,W0232,R0903,R0913,C0103,R0914,C0304,F0401,W0402,E1101,W0614,C0111,C0301” ] You stated that you started seeing … Read more

Pylint warning for “useless super delegation”

by

If you call the SpecificError class it will look for an __init__. If it doesn’t exist it will call the parent’s __init__. There is no need to add an __init__ here, since it’s exactly the same like the parent class. It is basically code duplication. You should do: class SpecificError(MyProjectExceptions): “””Raise when a specific error … Read more

So you may want to disable this message for this class, eg: class ExtendedRegisterForm(RegisterForm): # pylint: disable=too-many-ancestors
