You need to double the Modèle:And:

>>> x = " {{ Hello }} {0} "
>>> print x.format(42)
  { Hello } 42  

http://docs.python.org/library/string.html#formatstrings http://docs.python.org/library/string.html#formatstrings

Format strings contain “replacement fields” surrounded by curly braces {}. Anything that is not contained in braces is considered literal text, which is copied unchanged to the output. If you need to include a brace character in the literal text, it can be escaped by doubling: Modèle:And.
