how to grab pixel aspect using python

Hi , i’m making a gizmo, let’s name it a dummy node doing simple task. so when this node is connect to a tree , its label will simply display current pixel aspect ratio of its input stream. Does anyone know how to grab the pixel aspect from abritrary node? if it’s constant/checkerboard/read/etc , i can just easily grab it using .knob(‘format’). But what if let say the tree is like this :
constant1 –> blur1 –> transform1 –> dummy. So my dummy is placed below the transform node. Yes, if i want i can get it using .input(0).input(0)…..knob(‘format’) without problem. But this approach is not dynamic, if i insert something between constant1 and transform1 then the code will break. Try to search dir() but still got nothing about it. Anyone can help? or any other idea?

thanx.

Daft Punk vs Tron vs Tron Legacy

Mentre tutta una generazione è in attesa del Sequel, previsto per Dicembre 2010, è bene ricordare l’incredibile ventata di innovazione apportata dal primo Tron. Distribuito dalla Disney nel 1982, Tron rappresenta il primo vero tentativo di utilizzo di Computer Grafica in un lungometraggio e se già all’epoca fece scalpore, vederlo ora, col “senno del poi”, lascia veramente di stucco.
