# By default, a rule applies to all files within the extension for which it is specified (e.g. all .py files)
|
|
# There are three operators we can use to manually include or exclude files from linting for a rule:
|
|
# 'exclude': 'set([<path>, ...])' - if <path> is a filename, excludes that file.
|
|
# if <path> is a directory, excludes all files directly below the directory <path>.
|
|
# 'exclude_line': 'set([(<path>, <line>), ...])' - excludes all lines matching <line> in the file <path> from linting.
|
|
# 'include_only': 'set([<path>, ...])' - includes only those files where <path> is a substring of the filepath.
