# --enable=similarities". If you want to run only the classes checker, but have

# CERTBOT COMMENT
# 1) Once certbot codebase is claimed to be compatible exclusively with Python 3,
#    the useless-object-inheritance check can be enabled again, and code fixed accordingly.
# 2) Check unsubscriptable-object tends to create a lot of false positives. Let's disable it.
#    See https://github.com/PyCQA/pylint/issues/1498.
# 3) Same as point 2 for no-value-for-parameter.
#    See https://github.com/PyCQA/pylint/issues/2820.
# 4) raise-missing-from makes it an error to raise an exception from except
#    block without using explicit exception chaining. While explicit exception
#    chaining results in a slightly more informative traceback, I don't think
#    it's beneficial enough for us to change all of our current instances and
#    give Certbot developers errors about this when they're working on new code
#    in the future. You can read more about exception chaining and this pylint
#    check at
#    https://blog.ram.rachum.com/post/621791438475296768/improving-python-exception-chaining-with.
# 5) wrong-import-order generates false positives and a pylint developer
#    suggests that people using isort should disable this check at
#    https://github.com/PyCQA/pylint/issues/3817#issuecomment-687892090.
# 6) unspecified-encoding generates errors when encoding is not specified in
#    in a call to the built-in open function. This relates more to a design decision
#    (unspecified encoding makes the open function use the default encoding of the system)
#    than a clear flaw on which a check should be enforced. Anyway the project does
#    not need to enforce encoding on files so we disable this check.
# 7) consider-using-f-string is "suggesting" to move to f-string when possible with an error. This
#    clearly relates to code design and not to potential defects in the code, let's just ignore that.
