    If two or more consecutive interpolations are passed, they will be treated as separate interpolations and an empty string will be inserted between them. For example, the following code creates a template with a single value in the :attr:`~Template.strings` attribute:
 
    >>> from string.templatelib import Interpolation, Template
-   >>> greeting = Template(Interpolation("World"), Interpolation("!"))
+   >>> greeting = Template(Interpolation("World", "name"), Interpolation("!", "punctuation"))
