    A Python expression is essentially any bit of code that *is not* a
    Python *statement*.  For example, the Python statement 'a = 1'
    assigns "1" to the "a" variable. You cannot use this statement in
    DTML expressions.  Likewise, you cannot use the statement 'print
    "x"' in DTML.  It is not an expression.  Essentially, an
    expression must be a combination of values, variables, and Python
    *operators*.  To find out more about Python's expression syntax,
    see the "Python Tutorial":http://www.python.org/doc/current/tut at
    the Python.org web site.  For more information specifically about
    the differences between Python expressions and statements, see the
    "Variables, expressions, and
    chapter of *How To Think Like a Computer Scientist Using Python*.
