[Tutor] Splitting a string

[tee chwee liong]

hi all,
 
the code works:
####
s='00101'
found = False
for i,c in enumerate(s):
    if c == '0':
        print 'Lane fail',i
        found = True
    if not found: print 'All lanes PASS
#####
 
Result:
>>> 
Lane fail 0
Lane fail 1
Lane fail 3
>>> 
 
the enumerate is checking from left to right. is it possible check from right to left? 
for eg:s='00101'

Will give below result:
Lane fail 1
Lane fail 3
Lane fail 4

 
 
thanks
