pylintrc

# This pylint config was adapted from that of Chromium's depot_tools, found at
# https://src.chromium.org/svn/trunk/tools/depot_tools/pylintrc
#
# Usage: first, install pylint in your working environment (for instance,
# "pip install --user pylint" on DTS edge node). Then copy this file into your
# home directory, rename with a leading period (".pylintrc").
#
# pylint is not perfect. Do not feel obligated to fix, work around or suppress
# all warnings and errors. Instead, use it to fix common problems, improve
# compliance with the Google Python Style Guide, and understand the messages
# you choose to ignore. Add comments to the ones you think will improve
# code readers' understanding, above the "violating" lines.
#
# We will update this file as our style guide evolves. Feel free to open an
# issue to add your own thoughts.
