How to use the eventkit.event.Event.create function in eventkit

import eventkit as ev

            ev.Range(2, 5)[ev.Min, ev.Max, ev.Sum].zip()
            ->
            [(2, 2, 2), (2, 3, 5), (2, 4, 9)]

        The events in the fork can be combined by one of the join
        methods of ``Fork``.

        Args:
            targets: One or more events that have no source yet,
                or ``Event`` constructors that need no arguments.

        fork = Fork()
        for t in targets:
            t = Event.create(t)
            t.set_source(self)
            fork.append(t)
        return fork
