Decreasing for loops in Python impossible?

This is very late, but I just wanted to add that there is a more elegant way: using reversed

for i in reversed(range(10)):
    print i

gives:

4
3
2
1
0

for n in range(6,0,-1):
    print n
# prints [6, 5, 4, 3, 2, 1]

for n in range(6,0,-1)

This would give you 6,5,4,3,2,1

As for

for n in reversed(range(0,6))

would give you 5,4,3,2,1,0
