EmPy may work:

Your template would look something like:

myOutput = """\

The total cost is @invoice.total.

This order will be shipped to @invoice.contact at the following
address:

@invoice.address

This order was generated at @time.ctime()
"""

This could be instrumented with something as simple as:

 >>> import em, time
 >>> myOutput = """\
...
... The total cost is @invoice.total.
...
... This order will be shipped to @invoice.contact at the following
... address:
...
... @invoice.address
...
... This order was generated at @time.ctime()
... """
 >>>
 >>> class Invoice: pass
...
 >>> invoice = Invoice()
 >>> invoice.total = "$123.45"
 >>> invoice.contact = "Jack McCoy"
 >>> invoice.address = "1 Police Plaza\nNew York City, NY"
 >>> print em.expand(myOutput, globals())

The total cost is $123.45.

This order will be shipped to Jack McCoy at the following
address:

1 Police Plaza
New York City, NY

This order was generated at Thu Mar  6 18:41:58 2008
