I've done some Googling around on this and it seems like creating a here document is a bit tricky with Python. Trivial via triple-quoted strings if there's no need for variable interpolation but requiring a long, long formatted arglist via (%s,%s,%s,ad infinitum) if there is. So my question is:
Is there a way to produce a very long multiline string of output with variables' values inserted without having to resort to this wacky
"""v = %s"""%(variable)
business?
I have no idea what a "here document" is, but there are several alternatives to the "wacky" basic substitution with a tuple of values.
OP is looking for "heredoc" syntax; in, let's say, PHP this lets you do something like:
$foo = new foo(); $name = 'MyName';
echo <<<EOT
My name is "$name". I am printing some $foo->foo.
Now, I am printing some {$foo->bar[1]}.
This should print a capital 'A': \x41
EOT;AFAIK, there is no direct Python equivalent for this kind of syntax. Using a mapping like you suggested or the string.Template class in Python 2.4 still maybe improvements over what OP calls that "wacky" business.

The simplest uses a mapping type:
mydict = {'namedVal': 666} '''v = %(namedVal)s''' % mydict
Does that let you build whatever a "here document" is?
