How do I set frame_end in the scene using script when I switch between different actions?

Question

I have different animations in each action with different duration.

Is there a way to store the length of the duration in each action so that the frame_end can adjust accordingly to it?

bpy.data.scenes["Scene"].frame_end = (animationLength * 24)

only set my frame_end at the last loop in my for loop for creating multiple animation.

The following snippet will loop over all actions and prints the length in keyframes of each action, the scenes keyframe position is adjusted.

import bpy

frame=1
for action in bpy.data.actions:
    print( "action=%s" % action.name )
    print( "action length=%d" % action.frame_range.y)
    frame = frame + action.frame_range.y
    bpy.context.scene.frame_set( frame )
    print( "frame=%d" % frame)
