usage: pylint [options]
options:
-h, --help show this help message and exit
Commands:
Options which are actually commands. Options in this group are mutually exclusive.
--rcfile RCFILE Specify a configuration file to load.
--output OUTPUT Specify an output file.
--help-msg HELP_MSG [HELP_MSG ...]
Display a help message for the given message id and exit. The value may be
a comma separated list of message ids.

Generate a sample configuration file according to the current
configuration. You can put other options before this one to get them in
the generated configuration. The config is in the .toml format.
--long-help Show more verbose help.
Main:
--init-hook INIT_HOOK
Python code to execute, usually for sys.path manipulation such as
pygtk.require().
--errors-only, -E In error mode, messages with a category besides ERROR or FATAL are
suppressed, and no reports are done by default. Error mode is compatible
with disabling specific errors.
--verbose, -v In verbose mode, extra non-checker-related info will be displayed.
--enable-all-extensions
Load and enable all available extensions. Use --list-extensions to see a
list all available extensions.
--ignore <file>[,<file>...]
Files or directories to be skipped. They should be base names, not paths.
(default: ('CVS',))
--ignore-patterns <pattern>[,<pattern>...]
Files or directories matching the regular expression patterns are skipped.
The regex matches against base names, not paths. The default value ignores
Emacs file locks (default: (re.compile('^\\.#'),))
--ignore-paths <pattern>[,<pattern>...]
Add files or directories matching the regular expressions patterns to the
ignore-list. The regex matches against paths and can be in Posix or
Windows format. Because '\\' represents the directory delimiter on Windows
systems, it can't be used as an escape character. (default: [])
--persistent <y or n>
Pickle collected data for later comparisons. (default: True)
--load-plugins <modules>
List of plugins (as comma separated values of python module names) to
load, usually to register additional checkers. (default: ())
--fail-under <score> Specify a score threshold under which the program will exit with error.
(default: 10)
--fail-on <msg ids> Return non-zero exit code if any of these messages/categories are
detected, even if score is above --fail-under value. Syntax same as
enable. Messages specified are enabled, while categories only check
already-enabled messages. (default: )
--jobs, -j <n-processes>
Use multiple processes to speed up Pylint. Specifying 0 will auto-detect
the number of processors available to use, and will cap the count on
Windows to avoid hangs. (default: 1)
--limit-inference-results <number-of-results>
Control the amount of potential inferred values when inferring a single
object. This can help the performance when dealing with large functions or
complex, nested conditions. (default: 100)
--extension-pkg-allow-list <pkg[,pkg]>
A comma-separated list of package or module names from where C extensions
may be loaded. Extensions are loading into the active Python interpreter
and may run arbitrary code. (default: [])
--extension-pkg-whitelist <pkg[,pkg]>
A comma-separated list of package or module names from where C extensions
may be loaded. Extensions are loading into the active Python interpreter
and may run arbitrary code. (This is an alternative name to extension-pkg-
allow-list for backward compatibility.) (default: [])
--exit-zero Always return a 0 (non-error) status code, even if lint errors are found.
This is primarily useful in continuous integration scripts. (default:
False)
--from-stdin Interpret the stdin as a python script, whose filename needs to be passed
as the module_or_package argument. (default: False)
--source-roots <path>[,<path>...]
Add paths to the list of the source roots. Supports globbing patterns. The
source root is an absolute path or a path relative to the current working
directory used to determine a package namespace for modules located under
the source root. (default: ())
--recursive <yn> Discover python modules and packages in the file system subtree. (default:
False)
--py-version <py_version>
Minimum Python version to use for version dependent checks. Will default
to the version used to run pylint. (default: (3, 13))
--ignored-modules <module names>
List of module names for which member attributes should not be checked and
will not be imported (useful for modules/projects where namespaces are
manipulated during runtime and thus existing member attributes cannot be
deduced by static analysis). It supports qualified module names, as well
as Unix pattern matching. (default: ())
--analyse-fallback-blocks <y or n>
Analyse import fallback blocks. This can be used to support both Python 2
and 3 compatible code, which means that the block might have code that
exists only in one or another interpreter, leading to false positives when
analysed. (default: False)
--clear-cache-post-run <y or n>
Clear in-memory caches upon conclusion of linting. Useful if running
pylint in a server-like mode. (default: False)
--prefer-stubs <y or n>
Resolve imports to .pyi stubs if available. May reduce no-member messages
and increase not-an-iterable messages. (default: False)
--files The files to lint. The flag can also be omitted as pylint will try to lint
any file passed as argument. This can be used to set files to a directory
in a configuration file and invoke pylint by only typing pylint on the
command line. Any file passed as argument will overwrite any file set in
the configuration file. (default: [])
Reports:
Options related to output formatting and reporting
--output-format, -f <format>
Set the output format. Available formats are: 'text', 'parseable',
'colorized', 'json2' (improved json format), 'json' (old json format),
'msvs' (visual studio), 'github' (GitHub actions) and 'junit' (JUnit XML).
You can also give a reporter class, e.g.
mypackage.mymodule.MyReporterClass.
--reports, -r <y or n>
Tells whether to display a full report or only the messages. (default:
False)
--evaluation <python_expression>
Python expression which should return a score less than or equal to 10.
You have access to the variables 'fatal', 'error', 'warning', 'refactor',
'convention', and 'info' which contain the number of messages in each
category, as well as 'statement' which is the total number of statements
analyzed. This score is used by the global evaluation report (RP0004).
(default: max(0, 0 if fatal else 10.0 - ((float(5 * error + warning +
refactor + convention) / statement) * 10)))
--score, -s <y or n> Activate the evaluation score. (default: True)
--msg-template <template>
Template used to display messages. This is a python new-style format
string used to format the message information. See doc for all details.
(default: )

all. Valid levels: HIGH, CONTROL_FLOW, INFERENCE, INFERENCE_FAILURE,
UNDEFINED. (default: ['HIGH', 'CONTROL_FLOW', 'INFERENCE',
'INFERENCE_FAILURE', 'UNDEFINED'])
--enable, -e <msg ids>
Enable the message, report, category or checker with the given id(s). You
can either give multiple identifier separated by comma (,) or put this
option multiple time (only on the command line, not in the configuration
file where it should appear only once). See also the "--disable" option
for examples.
--disable, -d <msg ids>
Disable the message, report, category or checker with the given id(s). You
can either give multiple identifiers separated by comma (,) or put this
option multiple times (only on the command line, not in the configuration
file where it should appear only once). You can also use "--disable=all"
to disable everything first and then re-enable specific checks. For
example, if you want to run only the similarities checker, you can use "--
disable=all --enable=similarities". If you want to run only the classes
checker, but have no Warning level messages displayed, use "--disable=all
--enable=classes --disable=W".

Typecheck:
Try to find bugs in the code using type inference.
--ignore-on-opaque-inference <y or n>
This flag controls whether pylint should warn about no-member and similar
checks whenever an opaque object is returned when inferring. The inference
can return multiple potential results while evaluating a Python object,
but some branches might not be evaluated, which results in partial
inference. In that case, it might be useful to still emit no-member and
other checks for the rest of the inferred objects. (default: True)
--mixin-class-rgx <regexp>
Regex pattern to define which classes are considered mixins. (default:
.*[Mm]ixin)
