Call function with parameters ----------------------------- You can do: format(3.1415926, '.2f') But you can not do: parameters = (3.1415926, '.2f') format(parameters) With callwith, you can do similar thing: from callwith import CallWith as _ parameters = _(args, **kwargs) parameters(format) Rename `CallWith` to `Parameters`, `CallWith` is now a subclass of `Parameters`. Change Log ---------- 0.2.0 - Rename `CallWith` to `Parameters`, `CallWith` is now a subclass of `Parameters`.
