#1

for index, val in enumerate(reversed(list)):

　　print len(list) - index - 1, val

#2 

def reverse_enum(L):
　　for index in reversed(xrange(len(L))):
　　　　yield index, L[index]

L = [‘foo‘, ‘bar‘, ‘bas‘]
for index, item in reverse_enum(L):
　　print index, item

#3

L = [‘foo‘, ‘bar‘, ‘bas‘]

for index in reversed(range(len(L))):
　　print index, L[index]
