Um, don't print the string until after you're done replacing?  :-)

Seriously though, since there are no print statements, etc.., in your
posted code, it's hard to understand exactly what your problem is.

In any event, there is a neat method of "single-pass multiple string
substitution using a dictionary" here:
http://aspn.activestate.com/ASPN/Cookbook/Python/Recipe/81330  It uses
a regular expression, so I'd guess it wouldn't be to hard to get it to
work in multiline mode.
