Basically no. The error you're seeing is a nice noisy one, but even if you got past that, there'll be a LOT of incompatibilities. Unfortunately, a quick google search for 'pyscand' showed up.... places where you've asked this question, suggesting that nobody else uses this library. It looks like you're going to have to take a big step back and figure out what the library is doing for you, and reimplement that somehow. :( Good luck.
