:Note that this for loop "as is" doesn't do anything to the responses list... 
:it just strips an item, then discards it. Maybe this is the reason why it 
:doesn't have the desired effect?

Thanks to all who responded and pointed this out.

As I said, I was having a dumb moment. I certainly should have known
better.

I especially liked the solution:

responses = [item.strip() for item in responses]

That is really the coolest. (I'm still not good at the list
comprehensions thing.)

Certainly, I can:

>>> responses = messagebody.split(';;')
>>> print responses
['N\012', '\012no, cs student\012', '\012N\012', '\012no\012',
'\012S\012', '\012case-sensitive\012', '\012Y\012', '\012yes\012',
'\012N\012', '\012no\012', '\012']
>>> for item in responses:
	item = item.strip()

	
>>> print responses
['N\012', '\012no, cs student\012', '\012N\012', '\012no\012',
'\012S\012', '\012case-sensitive\012', '\012Y\012', '\012yes\012',
'\012N\012', '\012no\012', '\012']
>>> 


Of course, as has been pointed out, I'm not doing anything to the list
itself, only to the items and not reassigning them back to the list.

Thanks to all for the swift responses. I will now go dent my head a
bit...
