The fundamentals...

[Neil Schemenauer]

Its probably clearer use string.replace.  Using ?!ng's excellent
pydoc command:

    $ pydoc string.replace

    Python Library Documentation: function replace in string

    replace(s, old, new, maxsplit=-1)
        replace (str, old, new[, maxsplit]) -> string
        
        Return a copy of string str with all occurrences of substring
        old replaced by new. If the optional argument maxsplit is
        given, only the first maxsplit occurrences are replaced.


So you can do:

    boo = string.replace(". ", "\n")

In Python 2.0 or later you can use string methods:

    boo = boo.replace(". ", "\n")
