Registers a flag whose value is a whitespace-separated list of strings.

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

Any whitespace can be used as a separator.


  • name: str, the flag name.
  • default: list|str|None, the default value of the flag.
  • help: str, the help message.
  • comma_compat: bool - Whether to support comma as an additional separator. If false then only whitespace is supported. This is intended only for backwards compatibility with flags that used to be comma-separated.
  • 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.
