#Here is the Python program you requested.

    """Executes a function after this request.  This is useful to modify
    response objects.  The function is passed the response object and has
    to return the same or a new one.
    Example::
    @app.route(\/\)
    def index():
    @after_this_request
    def add_header(response):
    response.headers[\X-Foo\] = \Parachute\
    return response
    return \Hello World!\
    This is more useful if a function other than the view function wants to
    modify a response.  For instance think of a decorator that wants to add
    some headers without converting the return value into a response object.
