[Tutor] string iteration

[Glen Wheeler]

  Well, here is my typically newbie attempt...

length = 'abcdefghijklmnop'
data = 'abc'
resultant = ''
position = -1 ## because first spot is 0
for x in length:
    if position < (len(data) - 1):  ## len('abc') is 3, not 2.  so if the -1
was not there, it would try to iterate 4 times (0,1,2,3)
        position += 1
    else:
        position -= (len(data) - 1)
    resultant = resultant + data[position]
print resultant

  As you can see it's alot bigger and clunkier than Doug's attempt, but I
thought it best to give another solutional - the bigger and clunkier
something is the easier it is to understand (most of the time :).

  Glen.
