First, it helps if you tell us what you were expecting instead.

In your example, you have a list where you have replaced the 2nd element 
with the list itself. The [...] indicates that it is self-referential; 
there is no other way for it to display itself, because the contained 
reference also refers to itself.

 >>> values[1]
[0, [...], 2]
 >>> values[1][1]
[0, [...], 2]
 >>> values[1][1][1][1][1][1][1][1][1]
[0, [...], 2]
 >>> values[1][1][1][1][1][1][1][1][1] is values
True
