Can Pylint error checking be customized?

Question

I am using pydev where I have set up pylint. The problem is that even inside the comments, pylint reports warnings. I was looking to disable any sort of checking inside any line

Answer 1

Here is the custom check example, and another example easier to understand.

I was facing a problem similar to you. The following code is my solution. I customized one checker to forbidden import datetime.now. You can take it for reference ：

class TestChecker(BaseChecker):
    """
    find the check type in the following url:
    https://github.com/PyCQA/pylint/blob/63eb8c4663a77d0caf2a842b716e4161f9763a16/pylint/checkers/typecheck.py
    """
    __implements__ = IAstroidChecker

    name = 'test-checker'
    priority = -1
    msgs = {
        'W0001': (
            'You should not import "%s"',
            'import-datetime-returns',
            'Should not import datetime'
        ),
    }

    def __init__(self, linter):
        super().__init__(linter)
        # I use original pylint's ImportsChecker as a property
        # from  import **
        self.forbidden_import = ['datetime.datetime.now']
        self.forbidden_import_from = ['datetime.now', 'now']
        self.forbidden_import_attribute = ['datetime.now', 'now', 'datetime.datetime.now']

    #the function will be rewrited
    def visit_importfrom(self, node):
        names = [name for name, _alias in node.names]
        for item in names:
            for check in self.forbidden_import_from:
                if item == check:
                    self.add_message('W0001', node=node, args=item)

    def visit_import(self, node):
        names = [name for name, _ in node.names]
        for item in names:
            for check in self.forbidden_import:
                if check == item:
                    self.add_message('W0001', node=node, args=item)

    def visit_attribute(self, node):
        for check_attr in self.forbidden_import_attribute:
            if check_attr == node.as_string():
                self.add_message('W0001', node=node, args=check_attr)


def register(linter):
    linter.register_checker(TestChecker(linter))
