Into a bytecode object:

 >>> from compiler.pycodegen import ModuleCodeGenerator
 >>> from compiler.misc import set_filename
 >>> from compiler import parse
 >>>
 >>> tree = parse('foo = 42')
 >>> set_filename('<foo>', tree)
 >>> code = ModuleCodeGenerator(tree).getCode()
 >>> exec code
 >>> foo
 42

Into Python source code: <http://ecritters.biz/asttosource.py>.
