When running pylint on a python file it shows me warnings regarding TODO comments by default. E.g.:
************* Module foo
W:200, 0: TODO(SE): fi
Along with the solution posted by @sthenault where you could disable all warnings, Pylint also allows you to ignore a single line (helpful if you would want to deal with it in the future) like so:
A_CONSTANT = 'ugh.' # TODO: update value # pylint: disable=fixme
or by stating the Rule ID:
A_CONSTANT = 'ugh.' # TODO: update value # pylint: disable=W0511
