yes thank you
further down in the script..the collectionFile is indeed opened
and all it took was this line, to get the full program to work in python 3
**************
self.collFile=open(self.collectionFile,'r',encoding='utf-8')
******************

where 
,encoding='utf-8'
is the only change that had to be made, pointed out from INADA
(plus i used the 2to3.py, which corrected many print statements)

thanks alot for your efforts...im sure i will need this forum for future errors

thanks again to all who posted for this python 2 to python3 utf-8 unicodedecode error 
its very kind and built on the online programmers community spirit
