Same error as Stan above. Frank, can you post your working code?

Well, disregard my last comment. I was apparently way overdue to sleep last night. 0xD0 is a different sensor, that I have hooked up to my I2C bus aswell. I put the correct I2C address in my script today and wah la, querying the APDS 9660 with python works as expected. :)
