  I have downloaded python 2.7  with no problem. It works. I am trying to get pyserial to work. I have tried many different solutions. I am not  sure if it works or not. How can I be sure? I am using windows 7.  I did not see any help at python.org. Can you help?
PS my goal is make this adafruit project work.
