python - Assigning one list to another - Stack Overflow

listOne is pointing to the contents of the list. Then listTwo = listOne will just create another pointer (listTwo) to that same list.So when you do anything to either pointer, e.g. listTwo.append(4), you will affect the list that both listOne and listTwo are pointing to.
