Dynamic function calling

[Olaf Meyer]

I'm wondering if it is possible to call functions just by having access
to their name in a string value. Something similar to:

  def test():
     print "test function"

  f = "test"
  apply(f, ())

This does not work of course, because f does not have the right type.
Is there a way to get a function object from the name (string)?

Thanks,

  Olaf
