I don't think this does what you want:


    >>> "Foo %s" % {"foo": "bar", "bleh": "bloh"}
    "Foo {'foo': 'bar', 'bleh': 'bloh'}"
    >>> "Foo %s, %s" % {"foo": "bar", "bleh": "bloh"}
    Traceback (most recent call last):
      File "<stdin>", line 1, in <module>
    TypeError: not enough arguments for format string
