You are trying to loop thru the list and modify the items in place, it

When you rebind the item name to a new value ' ' it does not rebind the

Alternatively you can create a StringIO object and pickle that in your
dictionary so you can just load it later with PIL.
Pickling will bloat the size of your file so you might want to use some
compression, although most formats will compress very little the
pickling overhead can __mostly__ be avoided.
There are boundless ways to do this and this just one of them.

This will only create a tuple in memory that has no name to reference
it by!
How would you access the returned value?
If you want a tuple you need to assign all the return vales to a single
name.
mytup = abc(x,y,dotp,sumx,maxv)

The problem is why should this be the same:
