Just for completeness, you can also use lstrip(), rstrip() and strip() 
string methods to remove whitespace at the beggining, end or both parts 
of a string, respectively.  I.e.:

end_html = """
</BODY>
</HTML>
""".lstrip()

will get rid of the beginning newline.  Using strip(), will get rid of 
both.

I still prefer Mike's backslash solution, as getting rid of the newline 
is done at parse time rather than at run time.  Also lstrip() will eat 
too much space if the first line of the string ("</BODY") is indented 
(and you want to preserve that indentation).
