    Return ``True`` if there are only whitespace characters in the string and there is
    at least one character, ``False`` otherwise.
 
+   For example:
+
+   .. doctest::
+
+      >>> ''.isspace()
+      False
+      >>> ' '.isspace()
+      True
+      >>> '\t\n'.isspace() # TAB and BREAK LINE
+      True
+      >>> '\u3000'.isspace() # IDEOGRAPHIC SPACE
+      True

    A character is *whitespace* if in the Unicode character database
    (see :mod:`unicodedata`), either its general category is ``Zs``
    ("Separator, space"), or its bidirectional class is one of ``WS``,
    ``B``, or ``S``.
