Ok, I have the below code that runs on a Raspberry Pi. issue is that the below code works multiple times when I test but after a day or so it runs ie screen print is displayed and no crash or error but it does not sendmail. I am more a .net programmer so Python is very new to me and wanted to know if there is an obvious bug. or the best way to debug python. thanks in advance any help is greatly appreciated.

Fixed, I moved the while loop to include the msgRoot
