trying to change channels with python

[greggk1]

Thank you for the code.
I did try it. Parts of it work. I do see it handing off the channel number, but then I get an internal server error on the browser, and then command line I get the following error:

E:\Python>flask --app tv run

The image it's looking for it's in the same folder that the script is, and it worked before.
