Thanks for your help
I am not much closer in understanding this so I am going to try and start with a simpler example for myself. I will try and write some values to a file as I am struggling even doing this. TypeError: 'str' does not support the buffer interface TypeError: 'tuple' does not support the buffer interface these are the errors I tend to hit. So until I can write a list or a tuple to a file I will not try and get to adventurous. _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
