When Python's "print" statement/function is invoked, it will print the
textual representation of the object according to its class's __str__ or
__repr__ method. That is, the print function prints out whatever text
the class says it should.
For classes which don't implement a __str__ or __repr__ method, then
the text "<CLASS object at ADDRESS>" is used - where CLASS is the class
name and ADDRESS is the "memory pointer".

Look at the __iter__ method of the class of the object you are iterating
over. I suspect that it returns string objects, not the objects that are
in the list itself.
String objects have a __str__ or __repr__ method that represents them as
the text, so that is what 'print' will output.
Hope that helps, E.
