s.insert(-3, 0)
print s, s[-3], s[-4] # [1, 2, 3, 4, 5, 6, 0, 7, 8, 9] 7 0
So, I did insert 0 at index -3, but s[-3] is still 7, & 0 is in fact

problem now and don't see how to deal with it in a smooth way.
I have two csv files where:

somelist = [1,2,3,4]
newlist = []
for x in somelist:

somelist. If you need to actually modify somelist in place (ra

Still, a short passage has troubled my model about object names:
