Registers a flag whose value can be a list of any strings.

    name, default, help, flag_values=_flagvalues.FLAGS, **args

Use the flag on the command line multiple times to place multiple string values into the list. The 'default' may be a single string (which will be converted into a single-element list) or a list of strings.


  • name: str, the flag name.
  • default: Union[Iterable[Text], Text, None], the default value of the flag; see DEFINE_multi.
  • help: str, the help message.
  • flag_values: FlagValues, the FlagValues instance with which the flag will be registered. This should almost never need to be overridden.
  • **args: Dictionary with extra keyword args that are passed to the Flag init.
