How to call up addons within a script

Hello,

This has been asked before, and ive seen a few answers but im still stuck. I want to call this operator within my script.

#bpy.ops.turok_object.export_model()

It currently shows up under File/Export/Turok.

All i want to do is call it within another script im making to run a series of macros. Im fairly new to blender so part of my issue is finding out the terminology. Thanks!

Hello ! What exactly is not working as expected ?
