class Markup(str):
    """A string that is ready to be safely inserted into an HTML or XML
    document, either because it was escaped or because it was marked
    safe.

Passing an object to the constructor converts it to text and wraps
    it to mark it safe without escaping. To escape the text, use the
    :meth:`escape` class method instead.

>>> Markup("Hello, World!")
 Markup('Hello, World!')
 >>> Markup(42)
 Markup('42')
 >>> Markup.escape("Hello, World!")
 Markup('Hello &lt;em&gt;World&lt;/em&gt;!')

This implements the ``__html__()`` interface that some frameworks
    use. Passing an object that implements ``__html__()`` will wrap the
    output of that method, marking it safe.

>>> class Foo:
 ... def __html__(self):
 ... return '<a href="/foo">foo</a>'
 ...
 >>> Markup(Foo())
 Markup('<a href="/foo">foo</a>')

This is a subclass of :class:`str`. It has the same methods, but
    escapes their arguments and returns a ``Markup`` instance.

>>> Markup("%s") % ("foo & bar",)
 Markup('foo &amp; bar')
 >>> Markup("Hello ") + "<foo>"
 Markup('Hello &lt;foo&gt;')
