Python Pylint Runner to Pass (Exit 0) or Fail (Exit 1) Based on Pylint Score Threshold

lint.py

import argparse

from pylint.lint import Run


logging.getLogger().setLevel(logging.INFO)

parser = argparse.ArgumentParser(prog="LINT")

parser.add_argument('-p',
                    '--path',
                    help='path to directory you want to run pylint | '
                         'Default: %(default)s | '

if final_score < threshold:

    message = ('PyLint Failed | '
               'Score: {} | '
               'Threshold: {} '.format(final_score, threshold))

    logging.error(message)
    raise Exception(message)

else:
    message = ('PyLint Passed | '
               'Score: {} | '
               'Threshold: {} '.format(final_score, threshold))

    logging.info(message)

    exit(0)

Thanks for sharing the script.

But please note that for pylint >= 2.12.2 you will get TypeError: 'LinterStats' object is not subscriptable on line 36.
Please use results.linter.stats.global_note instead.

And for anyone looking to add a success threshold, since pylint 2.5.0 you can use a new argument called --fail-under

Example

pylint --fail-under=8 python_code.py

Damn I should have read this comment before forking this gist XD
