-To be done
-
+Also a Python script can be used in an animation cue. In the Python script three functions can be implemented:
+* start_cue: is executed once at the beginning of the animation
+* tick: is executed every time step
+* end_cue: is executed once at the end of the animation
+
+Here is an example of such a script. In this example the value of the timestep is translated into a date string (e.g. 2018-01-01) and displayed in the scene via a text source with name "Text1".
+{{{
+#!python
+from paraview.simple import *
+from datetime import date
+from datetime import timedelta
+
+def start_cue(self): pass
+
+def tick(self):
+    view = GetActiveView()
+    time = int(view.ViewTime)
+    dat = date(2000,1,1) + timedelta(days=time)
+    tx = FindSource("Text1")
+    tx.Text = repr(dat.year) + "-" + '{:02d}'.format(dat.month) + "-" + '{:02d}'.format(dat.day)
+
+def end_cue(self): pass
+}}}
