I copied your code here so others don't need to go fishing to see it :p
I have two comments without actually looking at the code too much...
1) Globals are bad, you should avoid them as much as possible, and
2) You only accept capital input, so a lowercase "b" is not valid. If you just make everything uppercase, that'd be nicer for the user:
>>> text = input("say something! ")
say something! spam
>>> text
'spam'
>>> text.upper()
'SPAM'
>>> text = text.upper()
>>> text
'SPAM'
