) forunnecessary-list-index-lookup
.Closes #9078
-
Fixed a crash in
symilar
when the-d
or-i
short option were not properly recognized. It's still impossible to do-d=1
(you must do-d 1
).Closes #9343
v3.2.3
False Positives Fixed
-
Classes with only an Ellipsis (
...
) in their body do not trigger 'multiple-statements' anymore if they are inlined (in accordance with black's 2024 style).Closes #9398
-

sys.exit()
) frompossibly-used-before-assignment
checks.Closes #9627
-
Don't emit
typevar-name-incorrect-variance

Restore "errors / warnings by module" section to report output (with
-ry
).Closes #9145
-
trailing-comma-tuple
should now be correctly emitted when it was disabled globally but enabled via local message control, after removal of an over-optimisation.Refs #9608
-
Add
--prefer-stubs=yes
option to opt-in to the astroid 3.2 feature that prefers.pyi
stubs over same-named.py
files. This has the potential to reduceno-member
errors but at the cost of more errors such asnot-an-iterable
from function bodies appearing as...
.Defaults to
no
.
Internal Changes
-
Update astroid version to 3.2.1. This solves some reports of
RecursionError
and also makes the prefer .pyi stubs feature in astroid 3.2.0 opt-in with the aforementioned--prefer-stubs=y
option.Refs #9139
v3.2.0
What's new in Pylint 3.2.0?
Release date: 2024-05-14
Of note: a github
reporter, two new checks (possibly-used-before-assignment
and contextmanager-generator-missing-cleanup
), performance improvements, and an astroid
upgrade providing support for @overload
and .pyi
stubs.
New Features
-
Understand
six.PY2
andsix.PY3
for conditional imports.Closes #3501
-
A new
github
reporter has been added. This reporter returns the output ofpylint
in a format that Github can use to automatically annotate code. Use it withpylint --output-format=github
on your Github Workflows.Closes #9443.
New Checks
-
Add check
possibly-used-before-assignment
when relying on names after anif/else
switch when one branch failed to define the name, raise, or return.Closes #1727
-
Checks for generators that use contextmanagers that don't handle cleanup properly. Is meant to raise visibilty on the case that a generator is not fully exhausted and the contextmanager is not cleaned up properly. A contextmanager must yield a non-constant value and not handle cleanup for GeneratorExit. The using generator must attempt to use the yielded context value
with x() as y
and not justwith x()
.Closes #2832
False Negatives Fixed
-
If and Try nodes are now checked for useless return statements as well.
Closes #9449.
-
Fix false negative for
property-with-parameters
in the case of parameters which arepositional-only
,keyword-only
,variadic positional
orvariadic keyword
.Closes #9584
False Positives Fixed
Performance Improvements
-
Ignored modules are now not checked at all, instead of being checked and then ignored. This should speed up the analysis of large codebases which have ignored modules.
Closes #9442
-
ImportChecker's logic has been modified to avoid context files when possible. This makes it possible to cache module searches on astroid and reduce execution times.
Refs #9310.
-
An internal check for
trailing-comma-tuple
being enabled for a file or not is now done once per file instead of once for each token.Refs #9608.
v3.1.1
What's new in Pylint 3.1.1?
Release date: 2024-05-13
False Positives Fixed
-
Treat
attrs.define
andattrs.frozen
as dataclass decorators intoo-few-public-methods
check.Closes #9345
-
Fix a false positive with
singledispatchmethod-function
when a method is decorated with bothfunctools.singledispatchmethod
andstaticmethod
.Closes #9531
-
Fix a false positive for
consider-using-dict-items
when iterating usingkeys()
and then deleting an item using the key as a lookup.Closes #9554
v3.1.0
Two new checks--use-yield-from
, deprecated-attribute
-- and a smattering of bug fixes.
New Features
-
Skip
consider-using-join
check for non-empty separators if ansuggest-join-with-non-empty-separator
option is set tono
.Closes #8701
-
Discover
.pyi
files when linting.These can be ignored with the
ignore-patterns
setting.Closes #9097
-
Check
TypeAlias
andTypeVar
(PEP 695) nodes forinvalid-name
.Refs #9196
-
Support for resolving external toml files named pylintrc.toml and .pylintrc.toml.
Closes #9228
-
Check for
.clear
,.discard
,.pop
andremove
methods being called on a set while it is being iterated over.Closes #9334
New Checks
-

use-yield-from
added to the refactoring checker. This message is emitted when yielding from a loop can be replaced byyield from
.Closes #9229.
-
Added a
deprecated-attribute
message to check deprecated attributes in the stdlib.Closes #8855
False Positives Fixed
-
Fixed false positive for
inherit-non-class
for generic Protocols.Closes #9106
-
Exempt
TypedDict
fromtyping_extensions
fromtoo-many-ancestor
checks.Refs #9167
False Negatives Fixed
-
Extend broad-exception-raised and broad-exception-caught to except*.
Closes #8827
-
Fix a false-negative for unnecessary if blocks using a different than expected ordering of arguments.
Closes #8947.
Other Bug Fixes
-
Improve the message provided for wrong-import-order check. Instead of the import statement ("import x"), the message now specifies the import that is out of order and which imports should come after it. As reported in the issue, this is particularly helpful if there are multiple imports on a single line that do not follow the PEP8 convention.
The message will report imports as follows: For "import X", it will report "(standard/third party/first party/local) import X" For "import X.Y" and "from X import Y", it will report "(standard/third party/first party/local) import X.Y" The import category is specified to provide explanation as to why pylint has issued the message and guidence to the developer on how to fix the problem.
Closes #8808
Other Changes
-
Print how many files were checked in verbose mode.
Closes #8935
-
Fix a crash when an enum class which is also decorated with a
dataclasses.dataclass
decorator is defined.Closes #9100
Internal Changes
-
Update astroid version to 3.1.0.
Refs #9457
v3.0.4
False Positives Fixed
-
used-before-assignment
is no longer emitted when using a name in a loop and depending on an earlier name assignment in anexcept
block paired withelse: continue
.Closes #6804
-
Avoid false positives for
no-member
involving function attributes supplied by decorators.Closes #9246
-
Fixed false positive nested-min-max for nested lists.
Closes #9307
-
Fix false positive for

in afinally
block when assignments took place in both thetry
block and each exception handler.Closes #9451
Other Bug Fixes
-
Catch incorrect ValueError
"generator already executing"
for Python 3.12.0 - 3.12.2. This is fixed upstream in Python 3.12.3.Closes #9138
v3.0.3
What's new in Pylint 3.0.3?
Release date: 2023-12-11
False Positives Fixed
-
Fixed false positive for
unnecessary-lambda
when the call has keyword arguments but not the lambda.Closes #9148
-
Fixed incorrect suggestion for shallow copy in unnecessary-comprehension
Example of the suggestion: #pylint: disable=missing-module-docstring a = [1, 2, 3] b = [x for x in a] b[0] = 0 print(a) # [1, 2, 3]
After changing b = [x for x in a] to b = a based on the suggestion, the script now prints [0, 2, 3]. The correct suggestion should be use list(a) to preserve the original behavior.
Closes #9172
-
Fix false positives for
undefined-variable
andunused-argument
for classes and functions using Python 3.12 generic type syntax.Closes #9193
-
Fixed
pointless-string-statement

inconsistent-quotes
for f-strings with 3.12 interpreter only if targeting pre-3.12 versions.Closes #9113
v3.0.1
False Positives Fixed
-
Fixed false positive for
inherit-non-class
for generic Protocols.Closes #9106
Other Changes
-
Fix a crash when an enum class which is also decorated with a
dataclasses.dataclass
decorator is defined.Closes #9100
v3.0.0
Pylint now support python 3.12 officially.
This long anticipated major version also provides some important usability and performance improvements, along with enacting necessary breaking changes and long-announced deprecations. The documentation of each message with an example is very close too.
The required astroid version is now 3.0.0. See the astroid changelog for additional fixes, features, and performance improvements applicable to pylint.
Our code is now fully typed. The invalid-name message no longer checks for a minimum length of 3 characters by default. Dependencies like wrapt or setuptools were removed.
A new json2 reporter has been added. It features an enriched output that is easier to parse and provides more info, here's a sample output.

Breaking Changes
-
Enabling or disabling individual messages will now take effect even if an
--enable=all
ordisable=all
follows in the same configuration file (or on the command line).This means for the following example,
fixme
messages will now be emitted:pylint my_module --enable=fixme --disable=all
To regain the prior behavior, remove the superfluous earlier option.
Closes #3696
-
Remove support for launching pylint with Python 3.7. Code that supports Python 3.7 can still be linted with the
--py-version=3.7
setting.Refs #6306
-
Disables placed in a
try
block now apply to theexcept
block. Previously, they only happened to do so in the presence of anelse
clause.Refs #7767
-
pyreverse
now uses a new default color palette that is more colorblind friendly. The color scheme is taken fromPaul Tol's Notes <https://personal.sron.nl/~pault/>
_. If you prefer other colors, you can use the--color-palette
option to specify custom colors.Closes #8251
-
Everything related to the
__implements__
construct was removed. It was based on PEP245 that was proposed in 2001 and rejected in 2006.The capability from pyreverse to take
__implements__
into account when generating diagrams was also removed.Refs #8404
-
pyreverse
: Support for the.vcg
output format (Visualization of Compiler Graphs) has been dropped.Closes #8416
-
The warning when the now useless old pylint cache directory (pylint.d) was found was removed. The cache dir is documented in
the FAQ <https://pylint.readthedocs.io/en/latest/faq.html#where-is-the-persistent-data-stored-to-compare-between-successive-runs>
_.Refs #8462
-
Following a deprecation period,
pylint.config.PYLINTRC
was removed. Use thepylint.config.find_default_config_files
generator instead.Closes #8862
Changes requiring user actions
-
The
invalid-name
message no longer checks for a minimum length of 3 characters by default. (This was an unadvertised commingling of concerns between casing and name length, and users regularly reported this to be surprising.)If checking for a minimum length is still desired, it can be regained in two ways:
-
If you are content with a
disallowed-name
message (instead ofinvalid-name
), then simply add the optionbad-names-rgxs="^..?$"
, which will fail 1-2 character-long names. (Ensure you enabledisallowed-name
.) -
If you would prefer an
invalid-name
message to be emitted, or would prefer finer-grained control over the circumstances in which messages are emitted (classes vs. methods, etc.), then avail yourself of the regex options describedhere <https://pylint.readthedocs.io/en/stable/user_guide/configuration/all-options.html#main-checker>
. (In particular, take note of the commented out options in the "example configuration" given at the bottom of the section.) The prior regexes can be found in thepull request <https://github.com/pylint-dev/pylint/pull/8813>
that removed the length requirements.
Closes #2018
-
-
The compare to empty string checker (
pylint.extensions.emptystring
) and the compare to zero checker (pylint.extensions.compare-to-zero
) have been removed and their checks are now part of the implicit booleaness checker:-
compare-to-zero
was renameduse-implicit-booleaness-not-comparison-to-zero
andcompare-to-empty-string
was renameduse-implicit-booleaness-not-comparison-to-string
and they now need to be enabled explicitly. -
The
pylint.extensions.emptystring
andpylint.extensions.compare-to-zero
extensions no longer exist and need to be removed from theload-plugins
option. -
Messages related to implicit booleaness were made more explicit and actionable. This permits to make their likeness explicit and will provide better performance as they share most of their conditions to be raised.
Closes #6871
-
-
epylint was removed. It now lives at: https://github.com/emacsorphanage/pylint.
Refs #7737
-
The
overgeneral-exceptions
option now only takes fully qualified names into account (builtins.Exception
notException
). If you overrode this option, you need to use the fully qualified name now.There's still a warning, but it will be removed in 3.1.0.
Refs #8411
-
Following a deprecation period, it's no longer possible to use
MASTER
ormaster
as configuration section insetup.cfg
ortox.ini
. It's bad practice to not start a section title with the tool name. Please usepylint.main
instead.Refs #8465
-
Package stats are now printed when running Pyreverse and a
--verbose
flag was added to get the original output with parsed modules. You might need to activate the verbose option if you want to keep the old output.Closes #8973
New Features
-
A new
json2
reporter has been added. It features a more enriched output that is easier to parse and provides more info.Compared to
json
the only changes are that messages are now under the"messages"
key and that"message-id"
now follows the camelCase convention and is renamed to"messageId"
. The new reporter also reports the "score" of the modules you linted as defined by theevaluation
option and provides statistics about the modules you linted.We encourage users to use the new reporter as the
json
reporter will no longer be maintained.Closes #4741
-
In Pyreverse package dependency diagrams, show when a module imports another only for type-checking.
Closes #8112
-
Add new option (
--show-stdlib
,-L
) topyreverse
. This is similar to the behavior of--show-builtin
in that standard library modules are now not included by default, and this option will include them.Closes #8181
-
Add Pyreverse option to exclude standalone nodes from diagrams with
--no-standalone
.Closes #8476
New Checks
-
Added
DataclassChecker
module andinvalid-field-call
checker to check for invalid dataclasses.field() usage.Refs #5159
-
Add
return-in-finally
to emit a message if a return statement was found in a finally clause.Closes #8260
-
Add a new checker
kwarg-superseded-by-positional-arg
to warn when a function is called with a keyword argument which shares a name with a positional-only parameter and the function contains a keyword variadic parameter dictionary. It may be surprising behaviour when the keyword argument is added to the keyword variadic parameter dictionary.Closes #8558
Extensions
-
Add new
prefer-typing-namedtuple
message to theCodeStyleChecker
to suggest rewriting calls tocollections.namedtuple
as classes inheriting fromtyping.NamedTuple
on Python 3.6+.Requires
load-plugins=pylint.extensions.code_style
andenable=prefer-typing-namedtuple
to be raised.Closes #8660

When checking for unbalanced dict unpacking in for-loops, Pylint will now test whether the length of each value to be unpacked matches the number of unpacking targets. Previously, Pylint would test the number of values for the loop iteration, which would produce a false unbalanced-dict-unpacking warning.

Internal Changes
-
get_message_definition
was removed from the base checker API. You can access message definitions through theMessageStore
.Refs #8401
-
Everything related to the
__implements__
construct was removed. It was based on PEP245 that was proposed in 2001 and rejected in 2006.All the classes inheriting
Interface
inpylint.interfaces
were removed.Checker
should only inheritBaseChecker
or any of the other checker types frompylint.checkers
.Reporter
should only inheritBaseReporter
.Refs #8404
-
modname
andmsg_store
are now required to be given inFileState
.collect_block_lines
has also been removed.Pylinter.current_name
cannot be null anymore.Refs #8407
-
Reporter.set_output
was removed in favor ofreporter.out = stream
.Refs #8408
-
A number of old utility functions and classes have been removed:
MapReduceMixin
: To make a checker reduce map data simply implementget_map_data
andreduce_map_data
.is_inside_lambda
: Useutils.get_node_first_ancestor_of_type(x, nodes.Lambda)
check_messages
: Useutils.only_required_for_messages
is_class_subscriptable_pep585_with_postponed_evaluation_enabled
: Useis_postponed_evaluation_enabled(node)
andis_node_in_type_annotation_context(node)
get_python_path
: assumption that there's always an init.py is not true since python 3.3 and is causing problems, particularly with PEP 420. Usediscover_package_path
and pass source root(s).fix_import_path
: Useaugmented_sys_path
and pass additionalsys.path
entries as an argument obtained fromdiscover_package_path
.get_global_option
: Usechecker.linter.config
to get all global options.Related private objects have been removed as well.

Following a deprecation period,
Pylinter.check
now only works with sequences of strings, not strings.Refs #8463

Following a deprecation period,
ColorizedTextReporter
only acceptsColorMappingDict

Following a deprecation period,
MessageTest
'send_line
andend_col_offset
must be accurate in functional tests (for python 3.8 or above on cpython, and for python 3.9 or superior on pypy).Refs #8466

Following a deprecation period, the
do_exit
argument of theRun
class (and of the_Run
class in testutils) were removed.Refs #8472
-
Following a deprecation period, the
py_version
argument of theMessageDefinition.may_be_emitted
function is now required. The most likely solution is to use 'linter.config.py_version' if you need to keep using this function, or to use 'MessageDefinition.is_message_enabled' instead.Refs #8473
-
Following a deprecation period, the
OutputLine
class now requires the right number of argument all the time. The functional output can be regenerated automatically to achieve that easily.Refs #8474
-
Following a deprecation period,
is_typing_guard
,is_node_in_typing_guarded_import_block
andis_node_in_guarded_import_block
frompylint.utils
were removed: use a combination ofis_sys_guard

Following a deprecation period, the
location
argument of theMessage
class must now be aMessageLocationTuple
