   It would be useful to have something like a getLevelNames method to return the current list of level names, ordered by priority.

   This currently appears to be available only by accessing a private member, like _levelToName or _nameToLevel.

   This functionality is useful, for example, in populating a choices list for an argparse option to allow a user to select a logging level when launching a program from a command line.

   I agree with you. It would be nice to have a function to list or dictionary of level names. Moreover I suggest that there should be an argument to the function like format_level which can take in "dict:level_name" for returning a dictionary with the level as keys and name as values, "dict:name_level" for returning a dictionary with the name as keys and level as values or "list" for returning just the list of level names ordered by priority.

   I can add getLevelNamesDict() which would return a copy of _nameToLevel, which is currently

   _nameToLevel = {
       'CRITICAL': CRITICAL,
       'FATAL': FATAL,
       'ERROR': ERROR,
       'WARN': WARNING,
       'WARNING': WARNING,
       'INFO': INFO,
       'DEBUG': DEBUG,
       'NOTSET': NOTSET,
   }

   I think it may be best not to return a list of levels because it's not obvious that some of them are aliases, if the caller is responsible for making the list out of the dict, they will be able to decide how to deal with alias levels.

   If that sounds good I can make a PR..

   That seem like the best approach.
