I'm
trying to understand the following piece of
code:
# node
list
n = []
for i in xrange(1, numnodes + 1):
tmp = session.newobject();
n.append(tmp)
link(n[0],
n[-1])
Specifically, I
don't understand what the index -1
refers to. If the index
0
refers to the first element, then what does
-1
refer to?

Negative
numbers mean that you count from the right instead of the left. So,
list[-1]
refers to the last element,
list[-2]
is the second-last, and so
on.
