I have recently started converting an IDL program to Python. I came across the a useful module for reading in IDL sav files however it only worked with Python 2. As I wanted to write my new program to be using the latest and greatest from the get go I decided to convert it to Python 3 and share it Python-3-IDLSave-0.9.7.zip

Let me know if you have any issues with it. Note: IDLSave requires Numpy.
