Seeing the above in a recent post, it made me wonder what would happen 
if the string had only two characters.  All went well and I'm wondering 
if I've stumbled across a solution to a problem I don't yet know 
about:-)

b, *m, e = 'abcdefghi'  # Length can be even or odd.
while m:
     print(b, m, e, sep='/')
     b, *m, e = m
