This is most likely what's going on. To the OP: please post the
relevant code, including

Your list probably contains several references to the same object,
instead of several different objects. This happens often when you use a
technique like:
list = [ object ] * 100
..because although this does make copies when "object" is an integer, it
just makes references in other cases.

The Problem (very basic, but strange):
I have a list holding a population of objects, each object has 5 vars
and appropriate funtions to get or modify the vars. When objects in
the list have identical vars (like all = 5 for var "a" and all = 10 for
var "b" across all vars and objects) and i chang
11 matches
