[Tutor] strange behavior in program

I believe that the lines where you prompt for again should be shifted to
the left so that they line up with
for char in original
This way the program will finish processing original before it asks
about looping again.
These are the lines to shift left.
again = raw_input("Would you like to convert more ....
if again in 'Yy':
again = True
elif again in 'Nn':
again = False
By shifting them left one level you take them out of the
for char in original
loop, but keep them in the
while again
loop.
I think that fits what you are really trying to do.
A minor suggestion. Your if/elif to set again could be replaced by:
again = again not in 'Nn'
again will be False when the raw_input is N or n or '', otherwise again
will be True. I think this matches what you actually coded and is much
shorter. Make sure that you follow what is happening. (The expression
looks a little funny since again is used to refer to the raw_input and
also to the loop control.)
