I have a module-level variable in my Python 2.6 program named \"_log\", which PyLint complains about:
C0103: Invalid name \"_log\" (should match (([A-Z_][A-Z
# pylint: disable-msg=C0103
Put it in the scope where you want these warnings to be ignored. You can also make the above an end-of-line comment, to disable the message only for that line of code.
IIRC it is true that pylint interprets all module-level variables as being 'constants'.
newer versions of pylint will take this line instead
# pylint: disable=C0103
